Murata SPM15 series isolated DC-DC converters represent the next generation in Industrial Potted Module Technology. Featuring a full 15-Watt output in one square inch of board area, the SPM15 series isolated DC-DC converter family offers effi cient regulated DC power for printed circuit board mounting. The 1" x 1" x 0.41" (25.4 x 25.4 x 10.41 mm) converter accepts a wide range of input voltages, ideal for industrial applications. Intended target markets include transportation, medical systems, electronic test equipment, industrial processing equipment, industrial applications where power modules must meet rugged environmental requirements, high power density, and where isolated output voltages are required. These converters offer a feature/option set including: through-hole mounting, positive or negative logic (remote on/off), over-current & over-temperature protection, under-voltage lockout. The input voltage range covers the standard Industrial requirements with a regulated output voltage and power rating up to 15W. Modules provide voltage isolation (basic insulation) from input to output of up to 1600V. The Operating Ambient Temperature Range is -40°C to +85°C. The Module delivers full output power to +70°C with no airflow. These parts are ideal for applications that do not require any heat sinking or forced air cooling.
