Category
The C22019218 surface-mount inductor provides reliable power filtering and voltage stabilization for consumer and industrial applications, with industrial-grade durability and ROHS compliance. Its compact design supports cost-effective integration into 4-layer PCBs while maintaining thermal efficiency through optimized winding techniques. The 2A continuous current rating and 500V voltage limit make it suitable for automotive ECUs and motor drives, though extended high-frequency use requires external shielding solutions.
