Product Overview
The WE-CFWI series Coupled Flat wire Inductor with low inductance drift over temperature. It is suitable for high power switching regulators, buck, boost, SEPIC, Cuk converter, 1:1 flyback converters and battery cell charging balancers.
- Very low RDC with tolerance of 10% only
- <lt/>0.5% Typical very low leakage
- Saturation current higher than 50A
- Coupled inductor with two identical windings
- More variants due to parallel and series connection possible
