1W DC/DC converter, input 12V +/-10%, output 5V/200mA, SMD

Low cost, low profile, open frame isolated 1Watt single output SMD DC/DC converter. The R1SX is available with 3.3V or 5V inputs and provides a single unregulated 3.3V or 5V output. There is no minimum load requirement and quiescent current consumption is less than 150mW. The standard isolation is 1kVDC/1s, a /H version with 3kVDC/1s is available. The operating temperature is between -40°C and +100°C without derating. The pin assignment corresponds to the industry standard and is compatible with the R1S series, but with half the height. The converters are fully certified to IEC/EN/UL62368 and IEC/EN/UL60950 and are 10/10 RoHS compliant. Only one input capacitor is required for Class A EMC compliance and only a simple, low cost LC filter is required for Class B EMC compliance. The standard packaging is tape and reel.
