REC3-0509SRW/H4/A/SMD

Product Overview

The REC3-0509SRW/H4/A/SMD from Recom Power is a surface-mount isolated DC DC converter module for board-mounted power subsystems. It accepts a 4.5V to 9V input and provides a single 9V output at up to 330mA, with a 3W rated output. The module includes 4kV isolation, an 83% efficiency figure, and an SCP feature, for use in compact commercial information technology and medical device power designs where input-to-output separation is required.

Key Features

• Type: isolated module with one output.
• Input range: 4.5V to 9V.
• Output: 9V at up to 330mA.
• Power: 3W.
• Isolation: 4kV.

• Operating temperature: -40°C to 80°C.
• Mounting: surface mount, 24-SMD module with 18 leads.
• Dimensions: 1.26in L x 0.78in W x 0.44in H (32.0mm x 19.9mm x 11.2mm).
• Feature: SCP.

Applications

• Commercial information technology equipment auxiliary power rails.
• Medical device isolated power subsystems.
• Embedded boards requiring a 9V rail from a 4.5V to 9V source.

Design & Procurement Notes

Designers should confirm that the available input remains within 4.5V to 9V and that the downstream load does not exceed 330mA or 3W. The 4kV isolation rating supports layouts that require input-to-output separation, while the 83% efficiency value helps estimate thermal dissipation at full load. The surface-mount 24-SMD package with 18 leads and the 32.0mm x 19.9mm x 11.2mm module height require adequate PCB land pattern, height clearance, and reflow compatibility. The -40°C to 80°C operating range and SCP feature are useful for compact ITE and medical power subsystems, but end-equipment designers should verify system-level safety, EMC, and overload protection requirements.
