• These inductors feature low DC resistance and high current
handling capacities, making them ideal for power supply line
applications.
• These are coaxial horizontal types, highly miniaturized and
lightweight.
• Available in ammo-pack style tape packaging to support
automated mounting machines.
APPLICATIONS
Televisions, VCRs, personal computers, and other electronic
equipment.

Rated current: Value obtained when current flows and the temperature has risen to 25°C or when DC current flows and the initial value of inductance has
fallen by 10%, whichever is smaller.
• Product’s part No. is changed as below by packaging style.
