The ETQ-P4M2R2KVK is a surface-mount, automotive-grade power choke coil from the PCC-M0840M-LP series, designed for high-reliability applications. It provides a nominal inductance of 2.2 µH, a typical DC resistance of 8.5 mΩ, and a saturation current of 20.4 A. Constructed with a metal composite core, this inductor ensures high heat resistance, excellent temperature stability, and operates over a wide temperature range of -55 °C to +155 °C. Its shielded, low-profile design makes it ideal for noise filtering in various drive circuits and for use in Boost and Buck DC/DC converters in demanding automotive environments.
