Würth Elektronik presents its WE-MXGI series power inductors for DC/DC converters

Waldenburg (Germany), July 10, 2024 – Würth Elektronik offers its WE-MXGI – a power inductor with unprecedented properties. Extremely low core losses, combined with the lowest winding resistance (RDC value) of all comparable products on the market to date, give rise to maximum efficiency in DC/DC converter applications. This was achieved by using an innovative core material and optimized winding geometry.

This makes the WE-MXGI magnetically shielded, compact SMT power inductor ideal for high-frequency DC/DC converter that utilize the latest GaN and SiC transistor technologies. The new WE-MXGI power inductor gives developers the opportunity to develop more efficient designs, to convert higher power levels, and to make their designs more compact.

So the WE-MXGI series is ideal for applications such as DC/DC converters for field programmable gate arrays (FPGA), POL-converters, portable power supplies such as PDAs or digital cameras, mainboards and graphics cards, battery-powered devices, wireless communication devices, power supplies for smartphones, tablet PCs and other mobile devices. The operating voltage is 80 V (DC) and the operating temperature ranges from -40°C to 125°C.

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

WE-MXGI is now available. Free samples are provided.
