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.

Toroids 2.54mm – 9.53mm
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.s from 2.54 mm to 140 mm) and materials (permeabilities ranging from 900 to 10,000), this section lists common sizes. For additional sizes contact Magnetics Sales. Toroid mounts and headers are available in a range of 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 and F material toroids are excellent choices for high frequency transformers. Special sizes in J material are available for Ground Fault Interrupter applications.

E, I Cores 12mm – 35mm
E 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. Bobbins for these different cross sections are available. E cores can be mounted in different directions and, if desired, provide a low profile. Printed circuit bobbins are available for low profile mounting. Typical applications for E cores include differential, power and telecom inductors, as well as, broadband, power, converter and inverter transformers.

Planar E, I Cores 14mm – 36mm
PLANAR E, I CORES Planar E cores are offered in all of the IEC standard sizes, as well as 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 especially useful for prototyping. I-cores are also offered standard, permitting further flexibility in design. E-I planar combinations are useful to allow practical face bonding in high volume assembly, and for making gapped inductor cores where fringing losses must be carefully considered due to the planar construction. Differential inductors and DCDC, ACDC converter are typical applications for planar cores.

ER Cores 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 nonplanar 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 inductors and power transformers.

PQ Cores 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 crosssectional area; thus cores tend to operate with fewer hot spots than with other designs.

Pot Cores 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 selfshielded geometry isolates the winding from stray magnetic fields or effects from other surrounding circuit elements. Both plain and printed circuit bobbins are available, as are mounting and assembly hardware. Typical applications for pot cores include; differential inductors, power transformers, power inductors, converter and inverter transformers, filters, both broadband and narrow transformers and telecom inductors.

RS-DS Cores 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. Both plain and printed circuit bobbins are available for both types of cores. Typical applications for RS-DS combinations include; low and medium power transformers, switched-mode power supplies, and converter and inverter transformers.

EP Cores 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.

Other Products from Magnetics 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 five permeabilities from 26µ through 125µ. Kool Mµ toroids are available in sizes identical to MPP cores, and extremely large (>4.0” or 101.6 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 1.938” (49.2 mm) and O.D.s from 0.140” (3.56 mm) to 3.063” (77.8 mm). Standard cores include either temperature stabilized (as wide as -65° C at 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 26µ through 160µ. High Flux cores are available in sizes identical to MPP cores.
Magnetics XF LUX ™ distributed air gap cores are made from 6.5% silicon iron powder. A true high temperature material, with no thermal aging, XF LUX ™ offers lower losses than powder iron cores and superior DC Bias performance. The soft saturation of XF LUX ™ material offers an advantage over ferrite cores. XF LUX ™ cores are ideal for low and medium frequency chokes where inductance at peak is critical. MPP THINZ ® are extremely low height (<1 mm) self-shielded power inductor cores, allowing finished inductor heights in the 1.5 mm to 2 mm range. THINZ come in 5 sizes with O.D.s ranging from 3.05 mm through 78 mm and four permeabilities: 125µ, 160µ, 200µ and 250µ. For further information view the Powder Cores Design Manual at www.mag-inc.com.
STRIP WOUND CORES
Tape wound cores are made from high permeability alloys of nickel-iron, grain oriented silicon-iron. The alloys are known as Orthonol ®, Alloy 48, Square Permalloy 80, Supermalloy 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 14 mils (0.356 mm). Cases are robust nylon boxes, rated for 200° C continuous operation and 2000 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 0.050”, with flux capacities as low as several maxwells. Magnetics’ sophisticated pulse test equipment reproduces most test programs and can measure accurately in the millivoltmicrosecond region. Applications include: magnetometers, flux gates, oscillators, inverters and magnetic amplifiers. For further information view the Strip Wound Cores Catalog at www.mag-inc.com.
