Product details

What the 1 kOhm common-mode impedance means for signal integrity

The TDK ACM3225-102-2P-T001 is a two-line common mode filter from the ACM series, packaged in a 1210 (3225 Metric) footprint with four leads for surface-mount assembly. 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.

Frequently asked questions

Is the ACM3225-102-2P-T001 discontinued?

Yes, TDK lists the ACM3225-102-2P-T001 as obsolete. No official replacement order code has been published. For existing designs, the part remains available through surplus and broker channels; new designs should evaluate current TDK ACM series common mode filters in the 1210 footprint.

What is the impedance of the ACM3225-102-2P-T001 at 100 MHz?

The common mode impedance is 1 kOhms at 100 MHz per line, specified for signal-line filtering applications where common-mode noise on differential pairs needs suppression without degrading the differential signal.
