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 Conducted EMI is transmitted via conductors such as wires or power lines. Radiated EMI Radiated EMI travels through the air without the use of a conductor.
