The WE-CFWI coupled flatwire inductor (74485540220) feature stable inductance and soft saturation. Targeting high-performance SEPIC, CUK, or buck/boost switching regulators, the inductors two 1:1 ratio coils handle from 12 to 28 A with an operating temperature of -40° to 150°C.
The device comes in a 1310 SMT case with seven versions with each winding having an inductance of 0.8 to 4.4 µH and a DCR of 1.6 to 9.6 mΩ. The units feature a leakage inductance of less than 0.5%. It costs $6.09 ea/300.
