UU Common Mode Choke

UU-type common mode chokes are a specific type of electromagnetic component whose core has a UU shape used in electronic circuits to suppress electromagnetic interference (EMI) and filter common mode noise.


UU-type common mode chokes find applications in a wide range of electronic circuits, and they are particularly effective for reducing conducted EMI and improving the electromagnetic compatibility (EMC) of electronic devices, including:

  • power supplies
  • motor drives
  • inverters
  • communication systems
