EMI/RFI Filters
EMI Filters, or electromagnetic interference filters, also called RFI Filters or radio-frequency interference filters, are an electrical device / circuit that mitigate the high frequency Electromagnetic noise present on the power and signal lines. The high frequency noise is generated by a variety of electrical and electronic devices such as motors, electronic controls, power supplies, inverters, clock circuits, microprocessors, appliances, electronic devices etc. This noise is typically in the 9KHz to 10GHz frequency range and it can degrade or prevent the signal transmissions and/or the intended performance of an electrical/electronic equipment. The lower frequency components of the EM noise can impact the power quality as well.
