The 5.5 Ohm max DCR sets the DC insertion loss — at 70 mA the self-heating from I²R is about 27 mW, negligible in a standard PCB layout but worth factoring into a dense power-stage thermal budget. ## AEC-Q200 qualification and 125°C operating ceiling Rated AEC-Q200 and qualified across -40°C to 125°C, this choke is specced for under-hood and engine-bay environments where the ambient temperature exceeds the 85°C commercial limit. The 80 VDC rating provides margin on 48 V automotive bus systems (ISO 7637-2 load-dump pulses can exceed 48 V nominal). ## Surface-mount footprint and tape-and-reel supply The 4-pad layout routes each line through two pads — the pair on each side are internally connected, so the PCB fan-out is straightforward: one trace enters, one exits per channel. Supplied on tape and reel (Cut Tape also available), the reel quantity suits medium-volume pick-and-place runs.","metaTitle":"TDK ACT1210L-201-2P-TL00 Signal Line Choke, 200 µH, 70 mA","metaDescription":"TDK ACT1210L-201-2P-TL00 common-mode choke, 200 µH at 100 kHz, 70 mA, 80 VDC, AEC-Q200.

This is the DC bias current the choke can carry without saturating the ferrite core or exceeding the temperature rise from DCR loss. For a 48 V CAN bus or a sensor power line drawing 50 mA, the choke has 20 mA headroom; for a 100 mA load, the inductance will roll off and the common-mode attenuation degrades."},{"question":"What compliance documentation does TDK provide for this part?","answer":"The ACT1210L-201-2P-TL00 is AEC-Q200 qualified (automotive passive component stress test qualification). TDK typically provides RoHS and REACH compliance declarations on request through the supply chain. No UL or IEC component-level certification is listed for this filter — the AEC-Q200 grade covers the automotive reliability screening."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/tdk-corporation/ACT1210L-201-2P-TL00","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/tdk-corporation/ACT1210L-201-2P-TL00 when reusing this data.
