"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.

 
 

 

EMI ( Electro-Magnetic Interference) and RFI ( Radio Frequency Interference) are generated when there are spikes in electronic signals. These occur in almost any types of electronic circuits when they are sharp rising and falling edges of currents and voltages waveforms.

In switching power supplies, the Mosfet switches will create these EMI or RFI noises. These need to be filtered to comply with the FCC and CE requirements, and also to prevent interference with the proper functioning of the electronic circuits.

The Common Mode Line Filters are used to block these noise on the power line.
