INDUCTOR

摘要

PROBLEM TO BE SOLVED: To provide an inductor for preventing low-loss characteristics from deteriorating and improving DC superposition characteristics and inductance. SOLUTION: In a choke coil (inductor) 1 in which a coil 3 is buried integrally in a core 2 formed by pressurizing the mixed powder where magnetic powder and binder are mixed, powder in which sendust power is mixed with carbonyl iron powder by 5-20 wt.% is used as the magnetic powder.
