R0.25S8-053.3-R

Product Overview

The Recom Power R0.25S8-053.3-R is a single-output isolated module DC-DC converter in the ECONOLINE R0.25S (0.25W) series. It accepts a 4.5V to 5.5V input and delivers a 3.3V output at up to 76mA, with a rated output power of 250 mW. The module provides 1 kV input-to-output isolation and uses an 8-SMD surface-mount package measuring 0.49 in L x 0.42 in W x 0.28 in H (12.8 mm x 10.7 mm x 7.0 mm). It operates from -40°C to 100°C, has 60% to 70% efficiency, and includes an SCP feature.

Key Features

• Single 3.3V isolated output with 1 kV input-to-output separation.
• Input range of 4.5V to 5.5V.
• Maximum output current of 76mA and output power of 250 mW.
• Surface-mount 8-SMD module with 12.8 mm x 10.7 mm x 7.0 mm dimensions.
• Operating temperature range of -40°C to 100°C and efficiency of 60% to 70%.
• SCP feature included for the converter module.

Applications

• Commercial information technology equipment requiring a 3.3V rail separated from a 4.5V to 5.5V supply.
• Low-current 3.3V circuits that need input-to-output isolation in a compact board area.
• Surface-mount board designs requiring a single 250 mW isolated power rail.

Design & Procurement Notes

Designers should verify that the upstream supply remains within 4.5V to 5.5V and that the 3.3V load does not exceed 76mA or the 250 mW output rating. The 1 kV isolation rating should be considered when separating input and output domains and defining board layout. Because efficiency is 60% to 70%, thermal layout should account for module dissipation, especially near the 100°C upper operating limit. The 8-SMD surface-mount package and 12.8 mm x 10.7 mm x 7.0 mm size require board area and surface-mount assembly considerations. The SCP feature should be considered in the final schematic and layout review for part number R0.25S8-053.3-R.
