Würth Elektronik SMD High-Current Coupled Inductors WE-CFWI

WE-CFWI high-current coupled inductors are equipped with two identical flat wire windings for high-current capabilities and ultra-low DC resistance for the best possible efficiency.

  • Very low DCR and very low leakage, typically <0.5%
  • Saturation current higher than 50 A
  • Low inductance drift over temperature
  • Operating temperature: -40°C up to +150°C
  • Coupled inductor with two identical windings
SMD High-Current Coupled Inductors WE-CFWI

Product Description

Würth Elektronik has just released its innovative SMD high-current coupled inductors WE-CFWI.
The inductors are equipped with two identical flat wire windings for high-current capabilities and ultra-low DC resistance for the best possible efficiency.
Currents of up to 50A with DCRs as low as 1.6 mΩ are possible, and like other Würth Elektronik high-current flat-wire inductors, the WE-CFWI range is rated for an operating temperature of -40°C up to 150°C.

Typical applications

Coupled inductors in SEPIC or CUK converters, high-current power inductors connected in serial, common mode choke for filtering in circuits with high currents, and 1:1 transformer for flyback applications or decoupling.

High efficiency

Two identical flat wire windings for high-current capabilities and ultra-low DC resistance help ensure the best possible efficiency.

Electrical characteristics

Currents of up to 50A with DCRs as low as 1.6 mΩ are possible.
