What are the key features of RI3-1205S?

  • Unregulated DC/DC power module for isolated board-level conversion
  • 12 V nominal input with 10.8 V to 13.2 V operating range
  • Single-function converter with 10% maximum load regulation
  • 4-pin SMA package for compact through-board power designs
  • Rated for -40 C to 85 C operating environments

What is RI3-1205S used for?

RI3-1205S is suited to industrial control electronics, distributed power rails, instrumentation interfaces, and communication modules that need a compact isolated DC/DC stage. It is commonly selected for 12 V bus designs where a simple unregulated converter can supply localized low-power circuitry.

Frequently Asked Questions

Which input bus should designers plan around for RI3-1205S?

RI3-1205S is built for a 12 V nominal input bus, with listed input limits from 10.8 V to 13.2 V for compatible system power planning.

How does load regulation affect use in sensitive circuits?

The listed maximum load regulation is 10%, so RI3-1205S works best where downstream circuits tolerate an unregulated rail or include local post-regulation.

What should procurement teams note about package and operating range?

The part is a 4-pin SMA power module rated for -40 C to 85 C operation, which helps buyers match footprint and temperature requirements before quoting.
