Hi Reliability and Ultra-Miniature SERIES A: Low Profile 0.5" x 0.5" x 0.30" Height! ...up to 1.25 Watts SERIES SM: Low Profile 0.5" x 0.5" x 0.340" Height! ...up to 1.25 Watts ALSO: New Series AT/DT 0.200 height - up to 0.75 Watts. (See table of contents) This series of unregulated DC-DC converters are produced in an ultra-miniature encapsulated package. 178 different models are available. The units feature single and dual outputs. They will operate over the temperature range of -25° C to + 70° C. No heat sink is required. FEATURES • Up to 1.25 watt output at 70° C ambient • Encapsulated semiconductors, conservatively rated for maximum reliability • Ultra-miniature size (0.3" Height) • 5 input voltage ranges 5, 12, 24, 28 and 48V DC • 100 megohm @ 500V DC isolation • Input/output isolation • Single and dual output • No heat sink required • Up to 250V Output Options Available • Per Mil Std. 883 • Expanded operating temp (-55° C to +85° C) • Stabilization Bake (125° C ambient) • Temperature Cycle (-55° C to +125° C) • Hi Temp, full power burn in (100% power, 125° C case temp) • TYPICAL CHARACTERISTICS: Test conditions: 25° C ambient and input voltage at nominal value unless otherwise specified. LINE REGULATION: OUTPUT IS DIRECTLY PROPORTIONAL TO THE INPUT.

No heat sink is required. Storage temperature: -55° C to +125° C Isolation: 100 megohms min. @ 500V DC, for 3.3 to 48 VDC out 100 megohms min. @ 1000 VDC for 100 - 250 VDC out.

* For units with output voltages up to 48 volts, ripple is measured with 10|jF, 75 volt high quality tantalum capacitor which is required across the output. * For units with output voltage of 100-250 volts use a 0.1|jF, 500 volt capacitor which is required across output, and maintain at least 10% of rated load to prevent a voltage surge. ** Maintain minimum 10% of rated load to prevent a voltage surge
