New common-mode choke for Lighting

ED100 and ED101 common mode chokes

Lighting LED drivers need to be high in efficiency, low in cost and compliant to EMC regulations. The ED100 / ED101 series increases the efficiency and reliability of a LED driver circuit by reducing the need for 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. Meet the new ED100 and ED101:

The twins with different characters.

ED100 - straight forward common-mode choke with high differential mode inductance

ED101 - same common-mode performance, but further increased differential mode inductance


The new design offers designers of LED drivers a few practical advantages: 

  • Space Saving on PCB; CM and DM inductances in one package
  • Choice of DM attenuation: high (ED100) / very high (ED101)
  • Rated currents 0.2A to 2 A; 18 products with same PCB pin layout
  • High reliability with MTBF of 13 million hours
  • Increased power factor and reduced earth leakage current by eliminating or reducing capacitors
