It is recommended to use high frequency and low resistance electrolytic capacitor. For capacitance and current of the capacitor please refer to suppliers’ specifications. Voltage derating of capacitor should be 80% or above.C2, C4 and C6 eliminate high frequency noise. TVS is a recommended component to protect post- circuits (when converter fails). 2. External input NTC is recommended to use 5D-9 (Only PPM10 model and PPM15 model) External Typical Value Partnumber C1 Partnumber C1 PPM05-A-3.3E 330 PPM15-C-3.3E 680 PPM05-A-05E 330 PPM15-C-05E 680 PPM05-A-09E 120 PPM15-C-09E 470 PPM05-A-12E 120 PPM15-C-12E 220 PPM05-A-15E 68 PPM15-C-15E 220 PPM05-A-24E 68 PPM15-C-24E 68 PPM15-C-48E 33 PPM10-B-3.3E 470 PPM10-B-05E 330 PPM20-D-3.3E 330 PPM10-B-09E 120 PPM20-D-05E 330 PPM10-B-12E 120 PPM20-D-12E 220 PPM10-B-15E 120 PPM20-D-15E 220 PPM10-B-24E 68 PPM20-D-24E 220 PPM25-D-12E 330 PPM25-D-15E 330 PPM25-D-24E 120 PPM25-D-48E 68 TRIM (only PPM20/25-D-xxE Note: Value for R1, R2, R3, and Vref refer to the following table.
