Frequently asked questions
What is the 200 Ohm impedance at 100 MHz actually filtering?
The 200 Ohms at 100 MHz targets common mode noise in the 100 MHz band — typical switching noise from DC-DC converters and digital clocks. The common mode choke presents high impedance to noise currents that are in-phase on both lines while passing the differential signal with minimal attenuation.
What package size is the ACM2012-201-2P-T002?
The 4 PC pad layout is specific to common mode chokes — two pads per side for the two signal lines.
