Würth Elektronik Presents Automotive High Current SMD Choke with Excellent Saturation

Würth Elektronik presents automotive SMD bar core choke WE-CHSA featuring high current inductance with excellent saturation behavior.

With the magnetically shielded bar core choke WE-CHSA Performance, Würth Elektronik expands its portfolio of qualified products for automotive applications.

The SMD 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.

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 coplanarity. 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 in 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.
