Its 900 Ohm impedance at 100 MHz targets the 30-300 MHz band where switching regulators and digital clocks radiate — a typical fit for the input or output of a buck converter feeding a sensor node or a small motor drive. ## Current handling and DC resistance Rated 2.3 A continuous with a maximum DC resistance of 60 mOhm. At full load the I²R loss is about 0.32 W, which the 4.70 x 4.50 mm horizontal package dissipates into still air up to 85°C ambient without forced cooling. The 50 V DC voltage rating gives headroom on 12 V, 24 V, and 48 V rails — just not 60 V+ bus voltages. ## Package and board fit Surface-mount in a horizontal, 4-pad configuration (package / case: Horizontal, 4 PC Pad). The two-line winding means one component filters both the supply and return conductors, saving board area over two separate ferrite beads. The ACM series is a power-line filter class, so it sits on the DC input or output of a converter — not on a signal line where a smaller bead would do.","metaTitle":"TDK ACM4520-901-2P-T000 Power Line Common Mode Choke","metaDescription":"TDK ACM4520-901-2P-T000 common mode choke, 900 Ohm @ 100 MHz, 2.3 A, 50 V DC, 60 mOhm DCR, -40 to 85°C.
