Fair-Rite Multi-Aperture Cores

Fair-Rite Multi-Aperture Cores are used in suppression applications and in balun (balance-unbalance) and other broadband transformers. These cores are employed in airbag designs to prevent accidental activation. The multi-aperture cores in 73 and 43 materials are measured for impedance on the E4990A impedance analyzer. These cores in 61 NiZn material are controlled for both impedance and AL value. The 61 and 67 material multi-hole beads are tested for AL value and the test frequency is 10kHz at <10 gauss. The 79 material product line continues to expand and include new geometries for power supply designs with operating frequencies up to 1MHz.

The 80 Material Manganese-Zinc ferrite has been tuned to operate in SiC and GaN switching power supplies with a stable temperature response for designs up to 5MHz. The 67 material exhibits superior performance up to 25MHz. With low losses and good temperature stability, this material has found a new purpose in switching power supplies above 5MHz. The 61 Material can be a great alternative to the 67 material in applications where higher permeability is valued over lower losses. This can lead to a high-performance overall component in some applications by limiting losses in the winding and shifting them to the core material.
