1.25W Isolated Proportional Low Profile DC-DC Converter Electronics, Inc. PRODUCT OVERVIEW The A & SM series are unregulated DC-DC converters in an ultra-miniature encapsulated package - 0.500” x 0.500” footprint. Over 200 models are available in both single and dual outputs. They can operate over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling. • Encapsulated semiconductors, conservatively rated for maximum reliability • Ultra-miniature size - down to 0.300” height • Input/output isolation • Single and dual output • No heat sink or derating required Contact Pico for part number of available options: • Expanded operating temp: -55°C to +85°C Stabilization Bake Temperature Cycle Burn-In • Available RoHS Compliant module • Special Input Voltage, Output Voltage, Isolation Voltage or Output Power A = THROUGH HOLE SM = SURFACE MOUNT

Note 2: For <48V output models, a 10pF, 75V high quality low ESR capacitor is required across the output. For >100V output models, a 0.1pF, 500V high quality low ESR capacitor is required across output. Note 3: Tested at nominal input voltage and full output load.
