Cx Family Common Mode Chokes
0402CT Low Profile Chip Inductors
XAL7050 High-inductance Shielded Power Inductors
XGL4020 Ultra-low DCR Power Inductors

Combination Line Filter Choke

RoHS compliant
  • Combines common and differential mode filtering in a single component
  • Can eliminate two extra filter chokes compared to standard common mode choke
  • Special windings and materials provides better filtering performance than common mode chokes or a single winding inductor alone
  • Refer to Designing Common Mode Filters for design guidance.
  • RoHS-compliant. Tin-silver over tin over copper terminations.
