Round Wire Coil Common Mode Choke Series

Pulse Electronics expands its range of surface mount common mode chokes with the introduction of the PA5140/41 series. Using the fully automated round wire coil forming technology developed for its existing high current inductor product line, these new series offer the highest available current in a surface mount package. Two platforms have been developed, the 18x19x19mm EP18 and the 23x23x23mm EP22 which offer inductances from 110uH to 470uH, with currents up to 32A. These EP cores have been designed around the coil dimension to minimize the component size, offering a higher-density inductance/current solution. The high permeability ferrite material minimizes the number of turns (and therefore the DC resistance) resulting in a much higher current rating that other similarly sized common mode chokes.

Key features:

  • Highest current surface mount common mode choke
  • 110uH to 470uH, with currents up to 32A
  • Higher current rating than similar sized components
