CMH, CMV Series

High Current Common Mode Chokes

符合RoHS
Our CMH/CMV Series of common mode chokes enhance power system performance with high-current capability. Designed to minimize electromagnetic interference (EMI) and optimize power transmission efficiency, these robust components are ideal for consumer electronics and demanding industrial applications such as telecom amplifier, base station, motor drives, inverters and converters, etc.
  • 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 30 MHz
  • Excellent current ratings – up to 40 A
  • Isolation (hipot) up to 3250 Vrms

注释
  1. Inductance shown for each winding. Measurement details are part number specific. See part number page in datasheet for details.
  2. 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.
  3. DCR is specified per winding.
  4. Isolation (hipot) measured for 1 minute.

端子:

  • RoHS compliant tin-silver over copper.
