What are the key features of RI3-0505S?

  • Unregulated DC-DC power module for compact board-level conversion
  • 4.5 to 5.5 V input range centered on nominal 5 V systems
  • Single-function 4-pin module format supports simple isolated rail layouts
  • 10% maximum load regulation figure supports early tolerance budgeting
  • Pb-free and REACH-compliant listing supports production compliance checks

What is RI3-0505S used for?

RI3-0505S is used in distributed power systems, industrial I/O boards, sensor interfaces, and control electronics that need a small DC-DC module around a 5 V rail. It suits designs where simple board-level conversion, electrical separation, and straightforward 4-pin assembly are more important than tight post-regulated accuracy.

Frequently Asked Questions

Which input rail should feed the RI3-0505S module?

The fetched specifications list a 4.5 to 5.5 V input range with 5 V nominal input, so it is intended for regulated 5 V source rails.

How much output tolerance should be considered in an unregulated converter design?

Because the part is an unregulated DC-DC module and the fetched data lists 10% maximum load regulation, downstream circuits should tolerate rail variation or add post regulation.

What PCB connection style does the RECOM RI3-0505S use?

The part is listed with an R-PSMA-P4 package code and 4 pins, which supports a compact through-hole module footprint for simple board assembly.

Where is this converter typically selected instead of a discrete supply?

It is selected for industrial sensors, isolated interfaces, and control boards that need compact 5 V DC-DC conversion within a -40°C to 85°C operating environment.
