The TDK ACM4520-421-2P-T000 is a 2-line common mode filter from the ACM series, designed to suppress conducted EMI on DC power lines up to 50 V. It delivers 420 Ohms of common mode impedance at 100 MHz, which is the typical frequency where switching noise from a DC-DC converter couples onto the input rail.
We source this active TDK part through authorized and independent distribution.
It provides 420 Ohms of common mode impedance at 100 MHz, which is the standard test frequency for EMI filter attenuation on power lines.
