active EMI filtercommon-mode EMIsingle-phase ACconducted emissionsSOT-23-THIN

TPSF12C1DYYR is a single-phase active EMI filter IC that senses common-mode noise and injects cancellation current through external Y-rated capacitors.

Best for

  • Single-phase offline power converters with common-mode EMI limits
  • High-density server power supplies
  • Industrial AC/DC power systems

Avoid if

  • The system has no suitable chassis-referenced auxiliary supply
  • Differential-mode EMI is the primary issue without a separate DM filter strategy

Check before use

  • Confirm common-mode noise is the dominant conducted-emissions issue
  • Tune the damping network for CM choke and injection-capacitor resonance
  • Use appropriately rated Y capacitors and an injection-side TVS clamp
