Würth Elektronik WE-CHSA P automotive bar core choke

Würth Elektronik’s WE-CHSA P (Performance) is a magnetically shielded bar core choke that is suitable for automotive applications.

The SMT high-current inductor represents an extension to WE-CHSA series featuring a newly developed core material, which helps it to achieve good saturation behaviour. The choke has a current carrying capacity of up to 28 A and an operating temperature range of ‑55 to +150°C.

The bar core choke series is available in sizes 1011, 1212 and 8090 and features a special product design with an air gap which should improve component tolerance, while the recessed solder pads enable optimum co-planarity. The core material enables 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. They can be ordered with different inductance values from 0.22 to 15 µH.
