The 0077256A7 is a toroid core manufactured using KOOL MU material in a 026 perm
Kool M? material?s low loss and relatively high saturation level (10,500 gauss) make it excellent for use in?power factor correction circuits (PFC)?as well as unidirectional drive applications. The near zero magnetostriction makes Kool M? (sendust) ideal for eliminating audible frequency noise in In-Line Noise Filters and Inductors.?
