Type 3657 Wirewound SMD Power Inductors

TE Connectivity's (TE) Holsworthy Type 3657 Wirewound SMD Power Inductors are engineered for high saturation current and low DC resistance, delivering high conversion efficiency and reduced temperature rise. These TE power inductors are designed with a magnetically shielded structure, offering enhanced electromagnetic compatibility (EMC) performance and high-resolution signal integrity. The Type 3657 series offers an inductance range of 0.1µH to 4.7µH and a saturation current range of 1.8A to 12.2A. Applications include smartphones/tablets, thin-type power supply modules, and DC-DC converters.
