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

FINEMET FT-3KM F series

FT-3KM F series cores made of FT-3M material are toroidal cores for common mode chokes for signal lines, DC power lines and AC power lines. FT-3M allows significant reduction of audible noise emission for the cores due to low saturation magnetostriction .

For the proper usage, please apply cables with appropriate rated voltage.
