EFD High Frequency Transformers

Power Transformers are used to convert voltages and isolate signals for functionality and safety.   Our broad line of catalog and custom solutions range from mW to 5-10kW and are used in multiple topologies including flyback, forward, push-pull, resonant, LLC and phase shifted full bridges.   Typical operating frequencies are between 80-500kHz but solutions can be adapted for greater than 1MHz operation.

Our designs include surface mount, through hole and pin-in-paste terminations using a wide range of winding technologies including wire-wound, flat wire, foil, copper plate and PCB constructions.    Our catalog and customer solutions include Class B (130C), Class F (155C) and Class H (180C) insulation systems for functional, basic and reinforced safety isolation requirements complying to the latest safety standards.
