Power inductors for DC-DC converters offer the lowest resistance and lowest losses

Würth Elektronik offers its WE-MXGI – a power inductor with outstanding properties. Extremely low core losses, combined with the lowest winding resistance (RDC value) of all comparable products on the market, give rise to maximum efficiency in DC-DC converter applications. This was achieved by utilising an innovative core material and optimised winding geometry.

This makes the device a magnetically shielded, compact SMT power inductor ideal for high-frequency DC-DC converters that use the latest GaN and SiC transistor technologies. The new power inductor allows developers to develop more efficient designs, convert higher power levels, and make their designs more compact.

The series is ideal for applications such as DC-DC converters for FPGAs, POL-converters, portable power supplies such as PDAs or digital cameras, mainboards and graphics cards, battery-powered devices, wireless communication devices, and power supplies for smartphones, tablet PCs, and other mobile devices. The operating voltage is 80VDC, and the operating temperature ranges from -40C to 125C.

The new power inductors are available in 4020 and 5030 packages whose inductances are 0.16µH to 4.7µH and 0.22µH to 10µH respectively with a saturation current of up to 28A. Further sizes and values are in development.
