6.7 kOhm common-mode impedance at 10 MHz
The ACT1210D-131-2P-TL00 is a 2-line common-mode filter from TDK's ACT1210 series, qualified to AEC-Q200 for automotive passive-component stress testing. Its 6.7 kOhm impedance at 10 MHz targets conducted emissions in the 10 MHz band — the typical noise region for CAN, LIN, and FlexRay differential buses. The 130 µH inductance at 100 kHz defines the choke's low-frequency roll-off; together these specs tell you the filter's stopband starts around 1 MHz and peaks in the 10-100 MHz range.
80 VDC rating and 125°C ambient
Rated for 80 VDC continuous, this filter handles a 48 V board net with headroom for load-dump transients; on a 12 V system the margin is generous. Current capacity is 115 mA max, so this is a signal-line filter, not a power-rail choke; feeding a 200 mA sensor supply through it would exceed the rating.
Horizontal 4-pad SMD footprint
The 4-pad layout is typical for a common-mode filter — two pads per winding — and the horizontal orientation keeps the profile low for tight PCB stack-ups. Supplied in Tape & Reel (TR) or Cut Tape (CT) for automated pick-and-place.
