The R1S-3.305-R is an unregulated 1W SMD DC/DC converter designed for low-power isolation and voltage matching applications. This device accepts a nominal 3.3VDC input and provides a single 5VDC output at up to 200mA, with a typical efficiency of 72-78%. Key features include a standard I/O isolation of 1kVDC/1s and a wide operating temperature range of -40°C to +100°C without derating. Supplied in tape and reel packaging for automated assembly, this converter is ideal for general-purpose and industrial applications where a compact, surface-mount solution is required.
