Filters type FIN1700E

HDT filters are designed to reduce electromagnetic interference (EMI), also called radio frequency interference (RFI, radio-frequency interference). EMI is a high-frequency disturbance that affects the electrical circuit due to inductions or electromagnetic radiation emitted from an external source. The EMI/RFI anti-interference filter is a passive electronic device used to eliminate the presence of conducted electromagnetic interference from the signal or the power line and to protect the device from electromagnetic interference signals present in the environment.
