The TDK ACM2012-900-2P-T002 is a wire-wound SMD common mode filter from the ACM2012 Series, designed for common-mode noise suppression on high-speed differential signal lines. It provides a typical common-mode impedance of 90Ω at 100MHz, with a minimum value of 65Ω at 100MHz, while maintaining low differential-mode impedance to minimize impact on high-speed signal transmission.
The device features a 2-line configuration, a rated current of 400mA, and a rated voltage of 50V DC. Maximum DC resistance is 190mΩ per line, while minimum insulation resistance is 10MΩ. Its compact dimensions of approximately 2.0 × 1.2 × 1.2mm make it suitable for space-constrained PCB designs.
The ACM2012 series is intended for common-mode noise suppression in high-speed differential interfaces, including USB, IEEE1394, Ethernet, LCD panel LVDS, and Panel Link lines. The ACM2012-900-2P-T002 operates from -40°C to +85°C and supports reflow and iron soldering. It is supplied on a 180mm reel with 8mm embossed plastic tape, with 2,000 pieces per reel.
TDK currently lists this part as Production (NRND – Not Recommended for New Design) and identifies MCZ1210AH900L2TA0G as a recommended alternate, while noting that interchangeability is not guaranteed.
