The series was tested by British Standards Institute (BSI) and received certificate number 8105 issue 2 confirming compliance with BS EN 60950 and IEC 950 safety standards for reinforced insulation. The NMJ series is suitable for applications where safety and miniaturisation are of paramount importance. EN 60950 is derived from IEC 950 and is equivalent to UL 1950 and CSA 950 standards. www.cdpoweronline.com See tolerance envelope High VIN to low VIN 10% load to rated load, 5V output types 10% load to rated load, 9V output types Load Regulation 10% load to rated load, 12V output types 10% load to rated load, 15V output types Ripple & Noise BW=DC to 20MHz, all output types Zero Load Power 5V output types Consumption 12V output types –7.5 1.0 10 6 6 6 275 185 % mV p-p mW ABSOLUTE MAXIMUM RATINGS Short-circuit duration3 Lead temperature 1.5mm from case for 10 seconds Input voltage VIN, NMJ05 types Input voltage VIN, NMJ12 types 1 second 300°C 7V 15V 1 Calculated using MIL-HDBK-217F with nominal input voltage at full load. 2 See derating curve 3 Supply voltage must be discontinued at the end of the short circuit duration.
