Power Supplies - Board Mount

3 W9-36 VDC input±3.3 VDC dual output1500 VDC isolationSIP-8RoHS

URA2403S-3WR2 is a 3 W isolated SIP-8 DC/DC module for converting a 9-36 VDC rail to regulated ±3.3 V outputs.

Best for

  • Generating isolated ±3.3 V rails from nominal 24 V systems
  • Industrial electronics and instrumentation
  • Compact through-hole power conversion

Avoid if

  • The application requires hot-plug support
  • Load current exceeds ±300 mA per output
  • A confirmed lifecycle or supply-chain qualification is required but unavailable

Check before use

  • Input remains within 9.0-36.0 VDC
  • Each output satisfies the minimum-load requirement
  • Output capacitors remain below the specified maximum capacitive load
  • SIP-8 pinout matches the physical module label
