EMI Line filter are used in electronic drive systems, machines and devices to reduce the high frequency interference voltage to a normal value. Valid norm which has to be respected to suppress interferences of drives is the EN61800-3-ff, for other power electrical devices it is the EN55011. These EMI Line filter are reaching a high damping caused by their two staged design. A C2 (EN61800) suppression level will be reached or class B (EN55011)
