Signal-line common mode choke, AEC-Q200 rated
The TDK ACT45B-220-2P-TL003 is a two-line common mode filter in the ACT45B series, designed to suppress conducted EMI on signal lines carrying up to 200 mA at 50 VDC. It delivers 1.2 kOhms impedance at 10 MHz and 22 µH inductance at 100 kHz, with a maximum DC resistance of 1 Ohm — the DCR figure sets the voltage drop and self-heating at the rated current, so a 200 mA load sees a 200 mV drop across the filter. Qualified to AEC-Q200, the part operates across -40°C to 150°C, covering under-hood and engine-bay temperature profiles in automotive electronics.
Supplied on tape and reel or cut tape, the package is compatible with standard pick-and-place assembly.
