5.1 kOhm common-mode choke for automotive signal lines
The TDK ACT1210D-101-2P-TL00 is a two-line common-mode filter in the ACT1210 series, designed to suppress conducted EMI on signal pairs in automotive and industrial electronics. Its 5.1 kOhm impedance at 10 MHz provides strong attenuation of common-mode noise in the 10–100 MHz range, where CAN, LIN, and sensor interfaces typically radiate. Rated for 150 mA continuous current and 80 VDC line voltage, it handles the typical 12 V / 24 V automotive bus with margin for transients.
AEC-Q200 qualification and temperature range
The 150°C upper limit suits engine-bay and exhaust-adjacent modules where standard 125°C parts would derate.
Horizontal 4-PC pad package for tight layouts
Inductance is 100 µH at 100 kHz, giving the filter a resonant frequency well above the common-mode noise band so the impedance stays inductive where it is needed.
