They are Input voltage VIN, NMA12 types 15V ideally suited for providing dual rail supplies on Input voltage VIN, NMA15 types 18V primarily digital boards with the added benet of galvanic isolation to reduce switching noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 1 watt. 1. Calculated using MIL-HDBK-217FN2 calculation model with nominal input voltage at full load. All specications typical at TA=25C, nominal input voltage and rated output current unless otherwise specied.
