Application Notes
 
"We will wind anything for you"

If you can conceptualize it, draw it, sketch it or describe it, we can wind it for you. Of course, if you have an engineering print of it, we can serve you even better.


Application Notes

This section contains useful application notes to assist engineers better understand various applications of ferrite for EMI suppression, use of transformers, inductors, chokes, etc.

Your feedback is very important for us to add more information to this section.

Understanding Properties of Magnetics, Inductors and Transformers
This describes some basic information about the properties of magnetics and how inductor and transformer work.
A short summary.

Reference Designs of Switch Mode Power Supplies using TOPSWITCH and TINYSWITCH
This section shows 8 different designs using Power Integration's TOPSWITCH and TINYSWITCH. These designs consist of a 1.3W ( 7.5Vo), 1.5W (9.0Vo), 3.6W (5.2Vo), 5W ( 5.0Vo), 15W (7.5Vo), 30W (15Vo), 13.55Vo and a 5 outputs circuits.

Advances in Power Sources
This article, written by K Kit Sum, gives a historical briefs on the advances in power supplies. It lists hundreds of references and sources for anyone who needed more information in the field of power supplies. A must read for students doing research on power supplies.

Understanding EMC Standards and Filter Specifications
This describes the EMC regulations and standards mainly for products sold to European countries as the EMC rules are strictly enforced in Europe.

Types of Surface Mount Inductors
Describes the various types of surface mount inductors - shielded from RFI/EMc radiations, unshielded types for lower cost, high current types, etc.

Types of Tape Wound Toroidal Cores
Describes types of tape wound cores and lamination transformers

What is a Transmission Line Transformer
Transmission line transformers are high frequency impedance matching devices over a wide freqeuncy range - typically 1 to 50 Mhz range at power rating of up to 10 kW. Designed by Dr. Jerry Sevick.
