Innovative Power Inductor
Ultra Low Losses. WE-MXGA.
Innovative Power Inductor
Ultra Low Losses. WE-MXGA.
With the WE-MXGA Würth Elektronik offers the newest molded power inductor series for automotive applications. It combines an innovative iron alloy material with an optimized wire geometry for lowest RDC and AC losses. This leads to high efficiency and current capability in a compact design. It is therefore ideal for DC-DC converters used in battery management systems (BMS) and infotainment or ADAS modules.
The innovative design in detail
Extremely High Power Density
Thanks to the innovative core material and the unique wire geometry, lower RDC values can be achieved.
In combination with the lower AC losses, the overall losses of your switching regulator can be reduced significantly.
