Its 1.4 kOhms impedance at 100 MHz targets conducted EMI on the DC bus — common-mode noise riding on the supply pair gets attenuated before it reaches the load or radiates from the cable. ## DC resistance and thermal budget The 1.5 A rating is the continuous current limit; derate for ambient above 85°C per the standard power derating curve for ferrite cores. ## Surface-mount footprint and placement The 4-pad layout provides separate input and output paths for each of the two lines, keeping the common-mode current path through the ferrite core. Tape-and-reel packaging supports automated pick-and-place.","metaTitle":"TDK ACM4520-142-2P-TL000 Power Line Common-Mode Choke, 1.5 A","metaDescription":"TDK ACM4520-142-2P-TL000 power line common-mode choke, 1.4 kOhms @ 100 MHz, 1.5 A, 80 mOhm DCR.
