Everything About EMI Filters

What is EMI Filters Electromagnetic interference filters (EMI Filters), also known as RFI Filters or radio-frequency interference filters, are an electrical device or circuit that reduces high-frequency electromagnetic noise on power and signal lines. There are various electrical and electronic devices, which produce high frequency noises such as motors, electronic controls, power supplies, inverters, clock circuits, microprocessors, appliances, and electronic devices.

EMI Filters Divided Into Two Parts  Conducted EMI

 Radiated EMI

Conducted EMI is transmitted via conductors such as wires or power lines.

Radiated EMI travels through the air without the use of a conductor.

Where Can EMI/RFI Come From It can be both Natural and Man-Made.  Natural Causes:

 Man-Made Causes:

 Lightning

 Electric motors and generators

 Solar flares and radiation

 Power supplies

 Dust and snow storms

 Cellular networks

 Electrical storms in the atmosphere

 Transmitters  Transformers

Why Do We Need a Power Line Filter  It is required due to the use of high frequency  Because of harmonic noise created from fast changes in voltage  And unwanted current from Switch Mode Power Supplies

Process for Selecting an EMI Filter  Review Electrical and Operational Requirements  Analyze Application and System Requirements  Review Actual EMI Filtering Characteristics  Preliminary EMC Testing

What is EMI Shielding and Why is it Important for Your Design?  EMI shield is a metal Shielding forms housing that blocks electromagnetic fields from radiating & coupling into other circuits or systems



EMI shields protect electrical devices from external radiation.
