Applications & Materials Ferrites are dense, homogenous ceramic structures made by mixing iron oxide with oxides or carbonates of one or more metals such as zinc, manganese, nickel or magnesium. They are pressed, then fired in a kiln at 1093° C, and machined as needed to meet various operational requirements. Ferrite parts can be easily and economically molded into many different geometries. Many diverse materials are available, providing many choices of desirable electrical and mechanical properties. Magnetics’ ferrite cores are manufactured for a wide variety of applications. Magnetics has the leading MnZn ferrite materials for power transformers, power inductors, wideband transformers, common mode chokes and many other applications.

Gapped Cores How To Order Part Number

Gapping for AL

0P44317

A450

Same as for ungapped cores Gap Code

When specifying and ordering E cores (including EC, EFD, EER, ETD, and Planar E cores) gapped to an AL, it is important to note which cores are produced in gap-to-gap combination, because two gapped pieces are assembled to achieve the AL. Alternatively, for E cores provided ungapped-togap, an ungapped piece must be used with a gapped part to achieve the AL. Pot, RS, DS, RM, PQ, and EP cores are sold as sets whether the combination is gap-to-gap or ungapped-to-gap.

Gap Code The letter indicates the type of gap and a three-digit number defines the value.

Code

In most applications, defining the gap with the AL results in inductors with the least variation. Electrical measurement is inherently more precise, and compensation is made for variability in material permeability and core geometry.

Meaning

Example

A_ _ _

AL (if <1000)

DF42311A275 (AL=275)

X_ _ _

AL if 1000 or greater (add 1000 to code)

OP44721X250 (AL=1250)

F_ _ _

AL if <100, non-integer (divide code by 10)

OR42510F807 (AL=80.7)

G_ _ _

Depth of Grind in mils (1000ths of an inch)

OF44317G079 (Gap=0.079”)

M_ _ _

Depth of Grind, mm (divide code by 10)

OF43019M015 (Gap=1.5 mm)

AL is inductance factor, mH/1000 Turns, or nH/T². Either the AL or the depth of grind (not both) is controlled during production of gapped cores. See the chart on pages 14-15 for tolerances.

Gap-to-Gap vs Ungapped-to-Gap Core Sets “Gap-to-gap combination” means the gap is symmetrical. Half of the total gap is removed from each piece. “Ungapped-to-gap combination” means an asymmetrical gap; the entire gap is taken from one piece, and the other piece is ungapped.

12 Gapped Cores - MAGNETICS

AL testing and limits are calculated to three significant digits, based on the normal value. For example, AL=99±3% is interpreted as 96.0 Minimum, 99.0 Nominal, and 102.0 Maximum. Magnetics tests gapped AL values with full bobbins, usually 100 turns, or 250 turns for deep gaps. The drive level is low (5 Gauss) and the frequency is set low enough to avoid resonance effects. Measured inductance in an application may vary significantly from the theoretical value due to low turns, low bobbin fill, leakage effects, resonance effects, or elevated drive levels. It is important for the users to verify the correlation between the test of the core and the specific test being applied to the inductor or transformer. Planar E cores, Planar RM, and Planar PQ cores are especially susceptible to correlation discrepancies.

Gapping for Depth of Grind For parts ordered in pieces (E and I cores). The depth of grind is given for each piece. For parts orders in sets, the depth of grind is given as a total for the set, and may be ungappedto-gap core pieces, or gap-to-gap. To make an ungapped-to-gap set, use one piece of each. For example, use 0R41808G050 with 0R41808EC for an asymmetrical gap of 0.050”± 001”. For the same gap, but symmetric, use two pieces of 0R41808G025. For deep gaps, however, better consistency often results when the depth of grind is specified. In such cases, variation in the finished inductor is dominated by the variation in the windings, especially if the number of turns is low.

Toroids

Ferrite toroids offer high magnetic efficiency as there is no air gap, and the cross sectional area is uniform. Available in many sizes (O.D. from 2.54 mm to 140 mm) and materials (permeabilities ranging from 900 to 10,000), this section lists common sizes. Typical applications for high permeability toroids (J and W materials) include common mode chokes, broadband transformers, pulse transformers and current transformers. L, R, P, F and T material toroids are excellent choices for high frequency transformers. Special sizes in J material are available for Ground Fault Interrupter applications.

E, I Cores

E cores are less expensive than pot cores, and have the advantage of simple bobbin winding plus easy assembly. E cores do not, however, offer self-shielding. Lamination size E cores are available to fit commercially offered bobbins previously designed to fit the strip stampings of standard lamination sizes. Metric and DIN sizes are also available. E cores can be pressed to different thicknesses, providing a selection of cross-sectional areas. E cores can be mounted in different directions and, if desired, provide a low profile.

9 mm – 35 mm

Typical applications for E cores include differential mode, power and telecom inductors, as well as, broadband, power, converter and inverter transformers.

EC Cores

A cross between a pot core and an E core, EC cores have a round center post that provides a wide opening on each side, and therefore, minimum winding resistance. The long legs support low leakage inductance designs. EC cores have standard channels for clamping assemblies. Plain bobbins, printed circuit bobbins and clamps are available for most sizes. Magnetics EC cores are typically used in differential mode inductor and power transformer applications.

ER Cores

ER cores are a cross between E cores and pot cores. The round centerpost of the ER core offers minimal winding resistance. In addition, they offer better space utilization and shielding than with rectangular center leg planar cores. When compared with non-planar cores, ERs offer minimal height and better thermal performance. E/I combinations facilitate economical assembly. Surface mount accessories are available. Typical applications of ER cores include differential mode inductors and power transformers.

Planar E, I Cores 14 mm – 36 mm

Planar E cores are offered in all of the IEC standard sizes, and a number of other sizes. The leg length and window height (B and D dimensions) are adjustable for specific applications without new tooling. This permits the designer to adjust the final core specification to exactly accommodate the planar conductor stack height, with no wasted space. Clips and clip slots are available in many cases, which is useful for prototyping. I cores are also offered standard, reducing path length and increasing inductance. Planar cores provide the lowest profile design. E-I planar combinations allow practical face bonding in high volume assembly. The flat back can accommodate a heat sink. Differential mode inductors, DC/DC, and AC/DC converters are typical applications for planar cores.

Block Cores

Ferrites can be pressed in block form and then machined into intricate shapes. Where large sizes are required, it is possible to assemble them from two or more smaller machined or pressed sections; the variety of sizes and shapes becomes limitless. Features of Magnetics Ferrite blocks include, low porosity, extreme hardness, uniform physical properties, high density and ease of machining. J material offers high permeability; R material is suitable for power applications.

EP Cores

EP cores are round center-post cubical shapes which enclose the coil completely except for the printed circuit board terminals. This particular shape minimizes the effect of air gaps formed at mating surfaces in the magnetic path and provides a larger volume ratio to total space used. EP cores provide excellent shielding. Printed circuit bobbins, surface mount bobbins and mounting clamp assemblies are available. Typical applications for EP cores include differential mode and telecom inductors and power transformers.

Pot Cores

The pot core shape is a convenient means of adjusting the ferrite structure to meet the specific requirements of an application. Both high circuit Q and good temperature stability of inductance can be obtained with these cores. Pot cores, when assembled, nearly surround the wound bobbin. This self-shielded geometry isolates the winding from stray magnetic fields or effects from other surrounding circuit elements. Typical applications for pot cores include; differential mode inductors, power transformers, power inductors, converter and inverter transformers, filters, both broadband and narrow, transformers and telecom inductors.

PQ Cores

PQ cores are designed specifically for switched mode power supplies. This design provides an optimized ratio of volume to winding area and surface area. As a result, both maximum inductance and winding area are possible with a minimum core size. The cores provide maximum power output with minimum assembled transformer weight and volume, in addition to taking up a minimum amount of area on the printed circuit board. Assembly with printed circuit bobbins and one piece clamps is simplified. This efficient design provides a more uniform cross-sectional area; thus cores tend to operate with fewer hot spots than with other designs. Typical applications include power transformers and power inductors.

RS-DS Cores

Slab cores are modified pot cores with the sides removed. The slabs can be paired with one round half of a standard pot core (RS combination) or two slabs can be paired together for a double slab (DS combination). The RS geometry offers all the advantages of pot cores for filter applications, plus many additional features for power applications. DS cores accommodate large size wire and assist in removing heat from the assembly. Typical applications for RS-DS combinations include: low and medium power transformers, switched-mode power supplies, and converter and inverter transformers.

UR Cores

UR cores are an excellent choice for high current designs and conditions where vibration occurs. The open window area accommodates large conductors. Holes through the center, or grooves on the outer legs of the core provide a method to secure the core to the PCB with mounting hardware. Typical applications include: the output transformer application in welding, audio amplifiers, traction and other high-power designs.

POWDER CORES

Powder cores are excellent as low loss inductors for switched-mode power supplies, switching regulators and noise filters. Most core types can be shipped immediately from stock. Kool Mµ® powder cores have a higher energy storage capacity than MPP cores and are available in six permeabilities from 14µ through 125µ. Kool Mµ toroids are available in sizes identical to MPP cores, and extremely large (>6.5” or 165 mm) toroids/shapes are possible with interlocking Kool Mµ segments. This material is also available in a number of E-core sizes. Permeability for Kool Mµ E-cores is from 26 to 90 and sizes are tooled ranging from the EF 12.6 to the 160LE size. Kool Mµ blocks and U cores are also available. Molypermalloy powder cores (MPP) are available in ten permeabilities ranging from 14 through 550, and have guaranteed inductance limits of ±8%. Insulation on the cores is a high dielectric strength finish not affected by normal potting compounds and waxes. Thirty sizes include I.D.s from 0.070” (1.78 mm) to 4.032” (102.4 mm) and O.D.s from 0.140” (3.56 mm) to 6.5” (165.1 mm). Standard cores include either temperature stabilized (as wide as -65° C to 125° C for stable operation) or standard stabilization. High Flux powder cores have a much higher energy storage capacity than MPP cores and are available in six permeabilities from 14µ through 160µ. High Flux cores are available in sizes identical to MPP cores. Magnetics XFLUX® distributed air gap cores are made from 6.5% silicon iron powder. A true high temperature material, with no thermal aging, XFLUX® offers lower losses than powder iron cores and superior DC Bias performance. The soft saturation of XFLUX® material offers an advantage over ferrite cores. XFLUX® cores are ideal for low and medium frequency chokes where inductance at peak is critical.

TAPE WOUND CORES

Tape wound cores are made from high permeability alloys of nickel-iron, cobalt-iron, and grain oriented silicon-iron. The alloys are known as Orthonol®, Alloy 48, Square Permalloy 80, Supermalloy, Supermendur and Magnesil®. Cores are available in more than 50 standard sizes. For a wide range of frequency applications, materials are produced in thicknesses from 1/2 mil (0.013 mm) through 4 mils (0.102 mm). Cases are robust nylon boxes, rated for 200° C continuous operation and 2,000 voltage minimum breakdown. Applications include: magnetic amplifiers, reactors, regulators, static magnetic devices and current transformers. Miniature Tape Wound Bobbin Cores are manufactured from Permalloy 80 and Orthonol ultra-thin tape (0.000125” to 0.001” thick). They are available in widths from 0.031” to 0.250” (wider on special request). Wound on non-magnetic stainless steel bobbins, core diameters are available down to 0.159”, with flux capacities as low as several maxwells.
