Flyback Transformers (ac line input)

Input range: Telecom (36 – 57 Vdc) Telecom (36 – 72 Vdc) | Telecom (14 – 72 Vdc) | 3.3 – 36 Vdc | 400 Vdc

These standard parts are available with opional tin-lead or tin-silver-copper terminations, which can improve the solder fillet and ensure an exceptionally reliable solder joint, and may also be available with an extended temperature range.

If no transformer meets your design criteria, review our application note Using Standard Transformers in Multiple Applications to determine if one of our other standard product offerings will work in your specific application.
