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. Co-planarity of the lead positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged. www.cdpoweronline.com MIN See tolerance envelope High VIN to low VIN 10% load to rated load, 0303M & 0503M 10% load to rated load, 5V output types 10% load to rated load, 0309M Load Regulation3 10% load to rated load, 0509M & 1209M 10% load to rated load, 0312M & 0315M 10% load to rated load, 0512M & 1212M 10% load to rated load, 0515M & 1215M BW=DC to 20MHz, 3.3V output types, NTA0305 & NTA0505ME BW=DC to 20MHz, all other 5V output types Ripple and Noise BW=DC to 20MHz, 9V output types BW=DC to 20MHz, 12V output types BW=DC to 20MHz, 15V output types ABSOLUTE MAXIMUM RATINGS Short circuit duration4 Internal power dissipation Lead temperature 1.5mm from case for 10 seconds Input Voltage VIN , NTA03 types Input Voltage VIN , NTA05 types Input voltage VIN , NTA12 types 1 2 3 4 5 Units 1second 700mW 300C 5.5V 7V 15V Calculated using MIL-HDBK-217F with nominal input voltage at full load.
