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.
