MAJOR USES
Noise lter for power source and automotive electrical unit
FEATURES
Low D.C. resistance due to the lead wire going through the core.
Use of a Fe-base amorphous core for excellent operational stability at high temperatures.
Surface-mount product for automotive.
Signicantly improved safety and reliability because layer short circuits will not occur and because the leakage magnetic ux is extremely
small.
