Obsolete — sourcing for existing BOM lines
The ACM3225-102-2P-T: The part is a 2-line signal line EMI filter in a 1210 (3225 Metric) surface-mount package with 4 leads, rated for 200 mA continuous current at 20 V DC.
What the impedance rating means for the line
The 1 kOhms impedance at 100 MHz is the common-mode suppression peak — it attenuates conducted noise in the 100 MHz band, typical for clock lines or high-speed data interfaces where the common-mode choke sits between the driver and the cable.
