Common mode choke for automotive signal lines
The TDK ACT45R-101-2P-TL001 is a 2-line common mode choke from the ACT series, designed to suppress conducted EMI on signal lines in automotive and industrial electronics. Its core impedance is 5.5 kOhms at 10 MHz, paired with 100 µH inductance at 100 kHz — this combination targets noise attenuation in the 1–100 MHz band typical of CAN, LIN, and sensor interfaces.
AEC-Q200 qualification and temperature range
Rated AEC-Q200, this choke is qualified for automotive-grade stress tests including thermal shock, vibration, and solder heat resistance — it suits under-hood and cabin electronics that see -40°C to +150°C ambient. The 50 VDC voltage rating and 200 mA continuous current limit are sized for low-power signal circuits, not power rails — the 1.5 Ohm max DCR keeps resistive voltage drop under 0.3 V at full current.
Package and board integration
Available on tape and reel (TR) or cut tape (CT), the ordering code suffix -TL001 denotes the reel quantity — confirm the packaging variant when placing the BOM line.
