High-temperature inductors resistant to thermal ageing

Würth Elektronik increases its moulded power inductors series with the high-temperature versions WE-MAPI and WE-LHMI. The new inductors can be used continuously at high-rated currents ranging from -55C to +150C. The compact components have been tested for thermal ageing for over 1000 hours at 200C and are qualified for AEC-Q200.

High temperatures in inductors with an iron alloy magnetic core result in thermal ageing. Core losses rise sharply, and efficiency drops. Ageing can lead to raised self-heating in the component, exacerbating thermal ageing. By extending its inductor series, the company now supplies power inductors that are unaffected by thermal ageing and do not suffer any performance loss.

The SMT power inductors deliver low losses, high efficiency, lightweight design, and a low package profile. Their high current-carrying capacity and capability of handling high transient current peaks can be used in applications such as DC-DC converters for high currents in power supplies, FPGA, POL converters, or CPU/RAM power supplies.

The high-temperature versions of both series are now available from stock. Free samples are available for developers.
