Its 1.4 kOhm impedance at 100 MHz targets conducted noise on DC power rails up to 50 V. Rated for 1 A continuous current with a maximum DCR of 80 mOhm, the filter's insertion loss is dominated by the common-mode impedance; the series resistance adds about 80 mV of voltage drop at full load, which is negligible for most 12 V or 24 V supply buses. ## AEC-Q200 qualification and temperature range The operating temperature range spans -40°C to 125°C, covering the full automotive ambient envelope including engine-bay heat soak. ## NRND — sourcing for existing designs This means the part remains available for existing production but is not intended for new BOMs.","metaTitle":"TDK ACM4520V-142-2P-TL00 Power Line CM Choke, 1.4 kOhm","metaDescription":"TDK ACM4520V-142-2P-TL00 common-mode choke, 1.4 kOhm @ 100 MHz, 1 A, 80 mOhm DCR, AEC-Q200, NRND.
