EMI Common Mode Suppression Inductors
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.
SURFACE MOUNT
Specifications
All units manufactured to Mil-PRF-27, Grade 5, Class S.
Dielectric Strength...1500 Volts RMS
Windings Balanced ± 1%
Maximum ambient plus temperature rise limited to 130º C.

These inductors are well suited for use in Switching Regulators, DC to DC Power Supplies, and all types of Electrical Equipment where the elimination of line transmitted Electromagnetic Interference is
important. Electrical equipment will generate noise due to switching operations of transistors, SCR's, replays, triacs, etc. By using these Inductors, noise being fed to the power line is minimized to an acceptable
level and this noise will not interfere with other equipment operating on the same power line.
