w a R r A r 1W Power in SMD package Features Pin compatible with R1S series DC/DC Converter -40C to +100C operating temperature full load High 3kVDC/1 second or 1kVDC/1 second isolation Unregulated IEC/EN/UL62368-1 certified, CB Report Converters 5000m operation R1SX Description 1 Watt Low cost, low profile, open-frame 1W SMD isolated DC/DC single output converters. The R1SX is avail- 3 able with 3.3V or 5V inputs and offers a single unregulated 3.3V or 5V output. There is no minimum SMD load requirement and the quiescent consumption is less than 150mW. Standard isolation is 1kVDC/1s and a /H version with 3kVDC/1s is available. The operating temperature is from -40C up to +100C Single Output without derating. The pin-out is industry standard and compatible with the R1S/R1D series, but at half the height. The converters are fully certified to IEC/EN/UL62368 and IEC/EN/UL60950 and are 10/10 RoHS-conform. Class A EMC conformity requires only an input capacitor and a simple low cost LC filter is all that is needed for Class B EMC. Standard packaging is tape and reel. Selection Guide Part nom.
