FERRITE BASE / LARGE CURRENT
WI - C
OUTLINE
The characteristics of this series perform low RDC and carry large current. Best for power supply applications such as PC, conveyable telephone, and other
FEATURES
Very strong solderability by reflow soldering and soldering iron. Highly accurate dimensions can be mounted automatically Terminals are highly resistant to pull forces. Highly resistant to mechanical shoks and pressure. Highly reliable in environments of sudden temperature change and humidity. Superior IDC for DC to DC converter.
