Approvals & Compliances

Lighting LED drivers need to be high in efficiency, low in cost and compliant to EMC regulations. The ED100 / ED101 series increases the efficiency of a LED driver circuit by reducing the need for X-capacitors. Thus, the power factor rises, and less unwanted reactive power is generated. The inductor is a combination of a strong common-mode inductance with a significant differential-mode inductance. It offers two filtering elements in one component. This helps the circuit designer to reduce the number of elements on the PCB, to reduce space requirement as well as lowering costs. Combined with the high MTBF value of the ED100 / ED101 series, a circuit design with reduced number of components profits for its overall reliability and lifetime.

Features and Benefits

  • Increases power factor
  • Combination of common- and differential-mode inductances
  • Rated currents up to 2 A
  • Compact and light-weight
  • Small PCB footprint

Typical Applications

  • Mains operated LED drivers
  • Electronic ballasts
  • Input filters for switch mode power supplies
