That impedance peak is where conducted EMI from switching regulators and digital clocks tends to radiate — the filter knocks down common-mode noise on the power rail without affecting the differential signal or DC current. Rated for 1.2 A continuous with a maximum DC resistance of 60 milliohms, the self-heating at full load stays under 90 mW — negligible for the 4.7 mm × 4.5 mm package. The 50 V DC rating covers 12 V, 24 V, and 48 V automotive and industrial rails with margin. Qualified to AEC-Q200, the automotive passive-component stress standard. It fits under-hood electronics, engine-control modules, and transmission controllers where the ambient sees 105°C plus self-heating.","metaTitle":"TDK ACM4520V-901-2P-T00 Power Line Filter, 900 Ohms, 1.2 A","metaDescription":"TDK ACM4520V-901-2P-T00 NRND power line common-mode filter, 900 ohms @ 100 MHz, 1.2 A, 50 V DC, AEC-Q200.
