Its primary spec is 1 kOhms impedance at 100 MHz on each line, which attenuates common-mode noise riding on differential signal pairs — think USB, Ethernet, or LVDS lines where the common-mode choke preserves the differential signal while choking out the noise that couples onto both conductors equally. ## Current, DCR, and the voltage ceiling Rated for 200 mA continuous current with a maximum DC resistance of 500 mOhm, the voltage drop across the filter at full rated current is 100 mV per line — negligible for a 20 VDC rail but worth factoring into the signal swing budget for low-voltage differential pairs. The 20 VDC rating covers the steady-state rail; the filter is intended for signal-line duty, not power-line filtering, so the current ceiling is the binding constraint for most designs. ## Obsolete — sourcing through independent channels TDK has marked the ACM3225-102-2P-T001 as obsolete. Operating from -25°C to 85°C, the filter suits indoor telecom, consumer electronics, and industrial control cabinets where ambient stays within that band.","metaTitle":"TDK ACM3225-102-2P-T001 Common Mode Filter, 1 kOhm @ 100 MHz","metaDescription":"TDK ACM3225-102-2P-T001 common mode filter, 1 kOhm @ 100 MHz, 200 mA, 20 VDC.
