Prem standard printed circuit power transformers feature a three flange design so that no electrostatic shield is required. Each unit is epoxy impregnated with 100% solids to withstand most aqueous and solvent printed circuit board cleaning systems. Pins are retinned after impregnation to ensure solderability. Every unit is final tested on automated panels for induced voltage (shorted turns), exciting current, open circuit voltage (turns ratio), polarity (phasing) and dielectric strength.

Prem's entire line of PC power transformers is UL Recognized and there is no extra charge for CSA Certification where offered. A cross reference guide to Microtran, Signal, Stancor and Triad part numbers is available for your convenience.
