TDK-EPC presents a new series of EPCOS 3-line EMC filters for frequency converters and other power electronics applications. The use of improved materials has led to a particularly cost-effective design of these input filters. All types of the B84143*166 series have UL/CSA approval and are designed for currents of 10, 20 or 35 A at rated voltages of 520 or 300 V AC. These filters satisfy protection class IP20 specifications and are suitable for operating temperatures of up to 50 °C.
