** The TEP 75WI series meets EMC characteristics only with external components connected before the input pin to the converter.

If customer only need to meet EN61000-4-4, EN61000-4-5, an external input lter capacitor is required. Recommended 1 pcs of aluminum

electrolytic capacitor (Nippon Chemi-con KY series, 220μF/100V, ESR 48mΩ) to connect in parallel. Recommended 2 pcs of aluminum

electrolytic capacitor (Nippon Chemi-con KXJ series, 150μF/200V) to connect in parallel.
