FINEMET FT-3KM N Series - COMMON MODE CHOKE CORES

FINEMET® FT-3KM N series

FT-3KM N series cores made of FT-3M material are toroidal cores for common mode chokes used in three-phase AC power lines.

FT-3M allows significant reduction of audible noise emission for the cores due to low saturation magnetostriction .
