R0.25S-2405-R

Product Overview

The Recom Power R0.25S-2405-R is an isolated module DC-DC converter that provides a single 5 V output from a 21.6 V to 26.4 V input. It delivers up to 50 mA and 250 mW, with 1 kV isolation between input and output. The surface-mount 8-SMD module with 5 leads measures 12.8 mm x 10.7 mm x 7.0 mm and operates from -40°C to 100°C. Efficiency is specified at 60% to 70%, and SCP is included. This converter is intended for commercial ITE applications and board-level isolated power conversion.

Key Features

• Single isolated 5 V output at up to 50 mA from a 21.6 V to 26.4 V input.
• 250 mW output power with 1 kV input-to-output isolation.
• Surface-mount 8-SMD module with 5 leads and a 12.8 mm x 10.7 mm x 7.0 mm footprint.
• Operating temperature range of -40°C to 100°C and efficiency of 60% to 70%.
• Includes SCP.

Applications

• Commercial ITE equipment that requires an isolated 5 V auxiliary rail.
• Isolated biasing of low-power board circuits where the input supply and load must remain separated.
• Compact surface-mount power conversion in designs constrained by a 12.8 mm x 10.7 mm x 7.0 mm module envelope.

Design & Procurement Notes

Design and procurement considerations should center on the converter's fixed electrical and mechanical limits. The input must remain between 21.6 V and 26.4 V, and the load should stay within 50 mA and 250 mW. The 1 kV isolation and SCP are relevant to board-level power design, while the 60% to 70% efficiency range should be included in thermal planning, particularly near the 100°C operating limit. The 8-SMD, 5-lead package requires surface-mount assembly and layout space for the 12.8 mm x 10.7 mm x 7.0 mm module. Before selection, verify that the 5 V output and commercial ITE application match the intended circuit function.
