COIL-SEALED IRON POWDER IMMIXED RESIN-MOLDED REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a coil-sealed iron powder immixed resin-molded reactor that suppresses inductance drop when a large amount of current is conducted while miniaturization is designed. SOLUTION: Inductance drop rate when the large amount of current is conducted can be reduced without increasing a body so much by suppressing iron powder filling ratio (weight of iron powder/weight of core) to 0.45-0.6, further preferably 0.5-0.55.
