The 10900703 (R1S-0505) is an unregulated 1W DC/DC converter in an SMD package, designed for low-power isolation and voltage matching applications. It accepts a nominal 5VDC input and provides a single 5VDC output with up to 200mA of current. This enclosed open-frame converter features a typical efficiency of 72-78% and provides 1kVDC/1s of input/output isolation. The device operates over a wide ambient temperature range of -40°C to +100°C at full power without derating, making it ideal for general purpose and industrial applications requiring a compact and reliable power conversion solution.
