The devices are fully compatible with CECC00802 to 280C which allows them to be placed and reflowed with IC's, thus reducing time and cost in production. The co-planarity of the pin positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged. www.cdpoweronline.com Ripple and Noise MIN See tolerance envelope High VIN to low VIN 10% load to rated load, 03XXM, 0503M, 0505ME 10% load to rated load, 0505M & 10% load to rated load, 0509M & 10% load to rated load, 0512M & 10% load to rated load, 0515M & BW=DC to 20MHz, 03XXM, 0503M, 0505ME types BW=DC BW=DC BW=DC BW=DC to to to to 20MHz, 20MHz, 20MHz, 20MHz, 0505M 0509M 0512M 0515M & & & & 1205M 1209M 1212M 1215M 1205M 1209M 1212M 1215M ABSOLUTE MAXIMUM RATINGS Short circuit duration4 Internal power dissipation Lead temperature 1.5mm from case for 10 seconds Input Voltage VIN , NTE03 types Input Voltage VIN , NTE05 types Input voltage VIN , NTE12 types 1 2 3 4 5 Units 1second 600mW 300C 5.5V 7V 15V Calculated using MIL-HDBK-217F with nominal input voltage at full load.
