Rated for 200 mA continuous current with a maximum DC resistance of 1.3 Ohms, the voltage drop and self-heating stay low enough for most digital interface or sensor lines. ## Board-fit and temperature envelope Operating from -40°C to 105°C, the choke covers the full automotive ambient range plus margin for self-heating under rated current. The 50 VDC voltage rating covers common automotive and industrial supply rails (12 V, 24 V, 48 V) with ample headroom.","metaTitle":"TDK ACM2012-681-2P-T001 Common Mode Choke, 680 Ohms","metaDescription":"TDK ACM2012-681-2P-T001 common mode choke, 680 Ohms @ 100 MHz, 200 mA, AEC-Q200.
