Chokes

common-mode chokeUU9.8through-holevertical12 mH4-pinEMI filter

A vertical UU9.8 common-mode choke with two 65-turn windings, specified for at least 12 mH per winding and up to 500 mΩ DCR.

Best for

  • Common-mode EMI filtering where a through-hole UU9.8 choke footprint is suitable
  • Low-frequency inductive filtering requiring at least 12 mH per winding

Avoid if

  • Rated current, impedance curve, or safety-isolation requirements must be documented
  • A compact surface-mount common-mode choke is required

Check before use

  • Confirm winding polarity and PCB pin mapping: N1 is 1-2 and N2 is 4-3
  • Validate DCR loss and temperature rise at the intended current
  • Confirm dielectric withstand requirements because the specification table has no completed limit
