Significantly smaller power inductors

Alpha-Core inductors are box shaped and fully encapsulated in black epoxy resin. Electrical product manufacturer Alpha-Core ( a division of Bridgeport Magnetics Group Inc.) has a new line of high-power inductors for high-frequency applications, such as on-grid solar power systems. The inductors are at least 30% smaller and lighter, because of using high-performance gapped amorphous ribbon cores instead of conventional cores of silicon steel or powdered iron. The Connecticut-based... Read More

New line of amorphous magnetic C-cores

Amorphous cores offer several advantages over cores made of silicon steel, ferrite, and powdered iron. With a higher saturation induction, the cores are half the size and weight. The ultra-thin lamination thickness of one mil (25 um) results in significantly lower core losses. Amorphous cores can operate at higher frequencies at the same flux level ,while conventional steel cores must operate at lower flux densities as the frequency increases. The cores also have a wide operating... Read More
