Output filtering capacitors C1, C2, and C3 are electrolytic capacitors, It is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance and current of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C2, C4, and C6 are used to filter high frequency noise and it is suggested that 0.1µF capacitors are used. TVS is recommended component to protect post-circuits (when converter fails). 2. External input NTC is recommended to use 5D-9 cui.com CUI Inc │ SERIES: VSK 15W │ DESCRIPTION: AC-DC POWER SUPPLY date 01/29/2013 │ page 6 of 6 REVISION HISTORY rev. description date 1.0 initial release 07/26/2011 1.01 V-Infinity branding removed 08/16/2012 1.02 added dual and triple output models 11/16/2012 1.03 updated derating curves 01/29/2013 The revision history provided is for informational purposes only and is believed to be accurate.
