Flyback Transformers

Many of Coilcraft's dc-dc and off-line switching converter transformers are stocked for immediate delivery and may be sampled at no cost.

These transformers also operate well in applications with power levels other than those shown and at a wide range of frequencies. The nominal frequency and circuit reference are only provided as a guide. Review our application note Using Standard Transformers in Multiple Applications to determine if one of our standard product offerings will work in your specific application.

If no transformer meets your design criteria, consider one of our versatile Hexa-path transformers. For more information about transformer design, download the Coilcraft Structured Design Guide for Switching Transformers for a step-by-step guide to transformer design or fill out the Power Transformer Design Worksheet.
