CMA Family

Automotive SMT Common Mode Chokes

The CMA family of automotive qualified common mode chokes provide high current capability, high frequency noise suppression, and high isolation voltage for automotive power electronics. Suitable for inverters, motor drives, onboard chargers, as well as telecom and industrial applications, the CMA series complements the Cx common mode choke series with AEC qualified reliability.

Solutions for use in a wide array of power line circuits
Ideal for use in consumer electronics and industrial applications
Suppression of high frequency common mode noise up to 100 MHz
Excellent current ratings – up to 8.2 A
Isolation (hipot) up to 1500 Vrms
Surface mount toroids
AEC-Q200 qualified

Notes

Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape. See packaging info below for tape and reel quantities.
Inductance shown for each winding. Measurement details are part number specific. See part number page in datasheet for details.
Current flows through both windings connected in series that causes a 40°C rise. This information is for reference only and does not represent absolute maximum ratings.
DCR is specified per winding.
Isolation (hipot) measured for 1 minute.

Termination:

RoHS compliant tin-silver over copper.
