The TDK ACM2012-900-2P-T001 is an automotive-grade, wire-wound surface-mount common mode choke designed for electromagnetic interference (EMI) suppression in signal transmission circuits. Featuring a typical common-mode impedance of 90Ω at 100MHz and a rated current of 400mA, this compact component helps reduce unwanted common-mode noise in differential signal lines.
Part of TDK’s ACM series, the ACM2012-900-2P-T001 provides a minimum common-mode impedance of 65Ω at 100MHz, a maximum DC resistance of 190mΩ, and a rated voltage of 50VDC. Its two-line configuration enables simultaneous common-mode noise suppression across paired signal conductors while helping preserve differential signal transmission.
With compact dimensions of 2.0 × 1.2 × 1.2mm, this common mode choke is suitable for high-density PCB layouts and automated SMT assembly. It operates over a temperature range of -40°C to +105°C and meets AEC-Q200 automotive qualification requirements.
The ACM2012-900-2P-T001 is suitable for automotive infotainment systems, multimedia interfaces, USB 2.0 signal lines, and other electronic communication circuits requiring effective EMI filtering and compact board-level integration.
