The 300 Ohms at 100 MHz impedance attenuates that common-mode current while leaving the differential signal intact. Rated for 20 V DC and 400 mA continuous, with a maximum DCR of 350 mOhm — the voltage drop across the winding at full current is 140 mV, which matters if the downstream receiver has a tight common-mode input range.","metaTitle":"TDK ACM2520-301-2P-T002 Common Mode Choke","metaDescription":"TDK ACM2520-301-2P-T002 signal-line common mode filter, 300 Ohms @ 100 MHz, 400 mA, 20 V DC, -40 to 85 °C.
