75 Material for Low-Frequency Suppression

Fair-Rite's 75 material, available in snap-it form, allows users to find solutuions to their low-frequency noise issues quickly. This material provides enhanced impedance between 150 kHz and 10 MHz making it superior to any other product available on the market and delivering twice the impedance at 1 MHz.

Ideal for cable assemblies, 75 material suppresses noise caused by conducted common-mode, low-frequency EMI from sources such as switching power supplies. Fair-Rite provides comparable impedances in both solid and snap-it cores, allowing users to troubleshoot their EMI issues knowing the performance will be analogous in their final product while requiring fewer turns and a shorter cable.
