- Notes: 1. The required C1 and C2 capacitors must be connected as close as possible to the terminals of the module; 2.  Refer to Table 1 for C1 and C2 capacitor values. For certain applications, increased values and/or tantalum or low ESR electrolytic capacitors may also be used instead; 

3. Converter cannot be used for hot swap and with output in parallel.
