Note:
① Use “H” suffix for heat sink mounting, “A2S” suffix for chassis mounting and “A4S” suffix for DIN-Rail mounting. We recommend to choose modules with a
heat sink for enhanced heat dissipation and applications with extreme temperature requirements;
② Absolute maximum stress rating without damage (not recommended);
③ Efficiency is measured at nominal input voltage and rated output load; efficiencies for A2S and A4S Model’s is decreased by 2% due to the input reverse
polarity protection circuit.

Design Reference
1. Typical application
All DC-DC converters of this series are tested before delivery using the recommended circuit shown in Fig. 2.
Input and/or output ripple can be further reduced by appropriately increasing the input & output capacitor values Cin and Cout and/or by
selecting capacitors with a low ESR (equivalent series resistance). Also make sure that the capacitance is not exceeding the max.
capacitive load value of the product.
