See Table 2 for EMC components. 2. TVS is a recommended component to protect post-circuits if converter fails. 3. C1 is a ceramic capacitor used to filter high frequency noise. 4. C2 is an electrolytic capacitor. We recommend using high frequency and low impedence electrolytic capacitors. For capacitance and current of capacitor please refer to the manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. 5. All specifications are measured at rated input voltage, rated output load, TA=25°C, and humidity < 75% unless otherwise specified. cui.com For more information, please visit the product page.
