Product details

Active automotive-grade common-mode filter — 90 Ohms at 100 MHz

The TDK ACM2012H-900-2P-T03 is an active-production common-mode filter from the ACM-H series, qualified to AEC-Q200 for automotive applications. Its 90 Ohm impedance at 100 MHz targets conducted-emission suppression on differential signal pairs like CAN, USB, and audio lines in 12V/24V vehicle electrical systems.

300 mA current, 300 mOhm DCR — the IR-drop budget for the signal pair

Rated for 300 mA continuous current per line with a maximum DC resistance of 300 mOhm. The 50V DC voltage rating provides ample headroom for 12V and 24V automotive buses, including load-dump transients clamped to 40V by the upstream TVS.

AEC-Q200 qualification (Grade 1 equivalent) means the part has passed the full suite of automotive reliability tests — thermal shock, moisture resistance, and solderability — per the AEC-Q200 stress test sequence.

0805 footprint, 2-line common-mode filter — board-fit note

The 2-line configuration suppresses common-mode noise on a single differential pair — one filter per CAN bus segment or USB differential pair.
