WE-LHMI High Current Power Inductors

The Wurth Electronics WE-LHMI series is an SMD power inductor with high saturation current and compact design with high-performance and space-saving design. The WE-LHMI is distinguished by high nominal and saturation currents. A special iron powder mixture prevents the saturation of the core across the entire operating range. It also provides magnetic shielding, which reduces the leakage field to a minimum and even eliminates acoustic noise. Areas of application for the WE-LHMI series include DC/DC converters in high-current power supplies to power field programmable gate arrays (FPGAs), POL converters, motherboards, graphics cards, and battery-operated equipment.

Available in case sizes: 4012, 4020, 5020, 5030, 7030, 7050, 8030, 8040, 1040, 1335, and 1365.
