CMN15 Series

Hi-Rel Nanocrystalline Common Mode Choke

Vanguard Electronics’ CMN15 Series is a high-reliability nanocrystalline common mode choke designed for demanding applications requiring high current handling and minimal DC resistance. With current ratings up to 20.1 A and DCR as low as 0.002 Ω, the CMN15 excels in power-dense designs, particularly those utilizing GaN technology or operating at high switching frequencies.

  • Wide inductance range (0.07 - 10.2 mH)
  • Current ratings up to 20.1 A
  • Moisture, Shock, and Immersion Resistant: Designed to withstand harsh environments.
  • Custom Designs and Modifications: Available in various sizes and package types.
