Its 90 Ohm impedance at 100 MHz targets common-mode noise coupling into high-speed data lines like USB 2.0, LVDS, or CAN bus, where the filter's common-mode choke structure attenuates unwanted currents without distorting the differential signal. ## NRND status and what it means for procurement This means the part is still available for existing production but is not intended for new board spins. For a buyer managing an active BOM, the NRND flag signals a planning window: confirm the remaining lifecycle commitment from your distributor and evaluate a pin-compatible alternative from the same ACM-D series or a broader common-mode filter family before the part enters end-of-life. The 4-pad layout connects the two signal lines through the common-mode choke — the outer pads carry the differential pair, and the inner pads are the common-mode return path. The 20 V DC voltage rating covers most low-voltage signal rails. The filter is supplied on tape and reel (Cut Tape also available), compatible with standard pick-and-place assembly.","metaTitle":"TDK ACM2012D-900-2P-T00 Common Mode Filter, 90 Ohm, NRND","metaDescription":"TDK ACM2012D-900-2P-T00 common mode filter, 90 Ohm @ 100 MHz, 300 mA, 20 V, NRND.
