1.4 kOhm common-mode choke for automotive power-line noise
The TDK ACM4520V-142-2P-TL00 is a 2-line common-mode filter from the ACM-V series, designed for power-line EMI suppression in automotive and industrial applications. 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.
