Electronics AEC-Q200-qualified automotive chokeWüRTH ELEKTRONIK WE-CHSA P series magnetically shielded bar core choke are AEC-Q200-qualified, suitable 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. Device achieves improved saturation behavior and has a current carrying capacity of up to 28A and an operating temperature range of -55°C to +150°C. Product 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 48.5A.
