The R1SX-3.305-R is an open-frame, 1W SMD isolated DC/DC converter designed to provide a single unregulated 5V output from a nominal 3.3V input. This converter delivers up to 200mA of output current with a typical efficiency of 78% and features a standard isolation rating of 1kVDC for 1 second. It operates across a wide temperature range of -40°C to +100°C at full load without derating and requires no minimum load. Its low cost, compact size, and robust performance make it suitable for applications requiring power isolation and voltage conversion, such as isolated bus interfaces, logic level translation, and industrial control systems.
