R1S12-3.305/H

Product Overview

The Recom Power R1S12-3.305/H is a 1 W isolated module DC DC converter from the ECONOLINE R1S (1W) series. It provides a single 5 V output at up to 200 mA from a 3 V to 3.6 V input, with 3 kV isolation and a surface mount 12-SMD module package. The converter is specified for operation from -40°C to 100°C and has an efficiency of 78%. Its compact 15.2 mm x 10.7 mm x 7.0 mm form factor supports board-level power conversion in commercial ITE and medical device contexts.

Key Features

• Isolated module DC DC converter with one output and 1 W power.
• Input range of 3 V to 3.6 V supports a single regulated 5 V output at 200 mA.
• 3 kV isolation provides galvanic separation between input and output.
• Surface mount 12-SMD module package with 10 leads and dimensions of 15.2 mm x 10.7 mm x 7.0 mm.
• Specified efficiency of 78% and operating temperature range of -40°C to 100°C.
• Includes SCP feature for use in board-mounted power conversion designs.

Applications

• Commercial information technology equipment requiring isolated auxiliary board power.
• Medical device subsystems needing galvanic isolation from a low-voltage source.
• Low-power 5 V auxiliary rails in surface mount commercial or medical assemblies.

Design & Procurement Notes

For design use, the converter requires an input source maintained within the narrow 3 V to 3.6 V range, so upstream regulation and transient margin should be checked. The 200 mA output limit should be considered when allocating load current, and the 78% efficiency value supports thermal planning for the surface mount module. Layout should preserve the 3 kV isolation boundary and accommodate the 7.0 mm module height. For procurement, specify the exact part number R1S12-3.305/H to identify this 3 V to 3.6 V input, 5 V output configuration. The SCP feature should be incorporated into the system protection approach rather than treated as a general input or output protection specification.
