Manufacturer of electronic and electromechanical components, Würth Elektronik has expanded its portfolio of AEC-Q-qualified products with a high current inductor. The patented ferrite core design of the new power choke has an air gap optimally centered to ensure a precisely defined saturation current. WE-CHSA can be used in the extended temperature range of 55°C to 150°C.

The patented product design with air gap enables extremely high saturation currents up to 54A.

The magnetically shielded package of the WE-CHSA assures a low stray field and the embedded solder pads offer optimal coplanarity while allowing good AOL (Automatic Optical Inspection) capability.

The rated current of the power choke extends to 28A. The product is available in package sizes of 8x8x9mm, 10x10x11mm and 12x12x12mm. For the rapid development phase, the complete series is available in a Design Kit.

WE-CHSA is particularly suitable for applications in the automotive industry, such as in powertrain control devices, in infotainment systems or in high current application for eMobility.
