EMI filters, or electromagnetic interference filters, are electronic passive devices used to suppress undesirable electromagnetic emission or any electronic disturbance which causes a malfunction or degradation in the performance of electrical equipment. An EMI Filter will suppress disruptions, enabling your device to function properly.
RFI filters, or radio frequency interference filters, electronic passive devices, are used to suppress undesirable electrical energy, conducted or radiated, within the frequency range dedicated to radio frequency transmission. As with an EMI Filter, an RFI Filter will suppress disruptions, allowing your equipment to function unhindered.
