Würth Elektronik Releases High-Temperature Power Inductors

Würth Elektronik supplements its molded power inductors series with the high-temperature versions: WE-MAPI and WE-LHMI.

The new inductors can be used continuously at high rated currents in a temperature range from -55°C to +150°C. The compact components have been tested for thermal aging for over 1000 hours at 200ºC and are qualified to AEC-Q200.

High temperatures in inductors with an iron alloy magnetic core result in thermal aging phenomena.

Core losses rise sharply and efficiency drops. Aging can lead to increased self-heating in the component, which in turn exacerbates thermal aging. By expanding its inductor series, Würth Elektronik now offers power inductors that are not only unaffected by thermal aging but also do not suffer any performance loss.

The SMT power inductors boast 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 utilized in applications such as DC/DC converters for high currents in power supplies or for field programmable gate arrays (FPGA), point of load (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.
