With the magnetically shielded bar core choke WE-CHSA Performance, Würth Elektronik expands its portfolio of qualified products for automotive applications.
The SMT high-current inductor represents an extension to the proven WE-CHSA series and differs from it only by a newly developed core material. As a result, WE-CHSA P - "P" as in performance achieves the best saturation behavior among comparable components on the market. The choke has a current-carrying capacity of up to 28 A and an operating temperature range of 55 °C to +150 °C.
Features of the WE-CHSA bar core choke
The WE-CHSA bar core choke series is available in sizes 1011, 1212, and 8090 and features a special product design with an air gap. This improves component tolerance, while the recessed solder pads ensure optimum co-planarity. The new core material enables extremely high saturation currents up to over 48.5 A (ΔL=10 %).
The AEC-Q200-qualified high-current inductors are suitable, for example, for use as input filter chokes in engine control systems or infotainment systems. A design kit and free samples are available for the product group. WE-CHSA P and WE-CHSA can be ordered immediately from stock with different inductance values from 0.22 to 15 µH without minimum order quantity.
