In the spirit of the season, CET Technology would like to wish everyone Happy Holidays and a Happy New Year with our Custom Magnetics Song! Enjoy! Twelve Days of CET Christmas On the first day of Christmas, CET sent to me A Toroidal Transformer for my radio and TV. On the second day of Christmas,…

Predicting the final temperature of a part is not always an easy thing to do. It becomes a complex task for complex parts. We’re going to predict this final temperature for something simple, like an air coil inductor. The mathematics found can “loosely” be applied to more complicated parts but certainly the approach can be…

In order to design a current sense transformer you need to determine the DCR of the SEC, the inductance of the SEC, the SEC wire area/gauge to use, the magnetic area of the core, the excitation current, the % error of the CT and the desired output voltage for a given input current. Let’s start…

Transformer voltage regulation for no load and full load voltages. So you’ve chosen a bobbin, wire, PRI turns, etc… now you want to spec an output voltage under LOADED conditions and determine the SEC turns needed to meet those voltages… Your output voltage drops when the SEC is LOADED compared when it’s at NO LOAD….

An audio transformer is used in audio circuits to block interference from radio frequencies and DC components…

If your company is looking for inductors, transformers, or power supplies CET Technology has the know-how and support to take any project from development to completion.

At CET Technology we are proud that our products meet the regulations required by RoHS (Restriction of use of Hazardous Substances).
