High Current Common Mode EMI Suppression Inductors

SURFACE MOUNT
PICO surface mount units utilize materials and methods to withstand extreme temperatures of vapor phase, I.R., and other reflow procedures without degradation of electrical or mechanical characteristics. 

Specifications

  • All units manufactured to Mil-PRF-27, Grade 5, Class S. 
  • Dielectric Strength...1500 Vrms
  • Windings Balanced ± 1%
  • Maximum ambient plus temperature rise: 130ºC maximum
  • Inductance Tolerance: ± 20%.
  • Moisture Sensitivity Level: MSL3

Pico's high current, small footprint industors are well suited for use in high current DC-DC power supplies, AC-DC power supplies, and other types of electrical equipment where the elimination of Common Mode noise is required. Common Mode noise is noise that is generated on the power lines due to switching of MOSFETS, SCR, and the like. The noise being fed back into the system is significantly reduced by these inductors.
