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.

• Low current Surface Mount EMI Filter Inductor

• High Current Surface Mount Toroidal Differential Mode Choke

• Low Power Line Filters for Video Signals

• High Power Common Mode Line Filters Chokes

• Toroidal Low Current ( 1 to 2 Amps) Common Mode Line Chokes

• Toroidal High Current ( 3 to 15 Amps) Common Mode Line Chokes

• Rod Type High Current Vertical and Horizontal Mount Differential Mode Chokes

• Rod Type Low Current Axial Leaded Differential
  Mode Chokes

• Toroidal Differential Mode Chokes with mounting Header (Base)

• Toroidal Differential Mode Chokes without Header (Base)
