RE-123.3S Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area (at least 1 cm²) connected to the module's thermal pad, and multiple vias to dissipate heat efficiently.
  • Yes, the RE-123.3S is designed to withstand vibrations up to 10G (10-2000 Hz) and shocks up to 50G (11 ms), making it suitable for industrial and transportation applications.
  • RECOM recommends derating the output power by 2.5% per °C above 40°C to ensure reliable operation. Additionally, ensure good airflow and a low thermal resistance PCB layout.
  • RECOM recommends using a low-ESR capacitor (e.g., X7R or X5R ceramic) with a value of 10-22 μF, depending on the input voltage and ripple requirements.
  • Yes, you can parallel up to 5 modules to increase the output power, but ensure that each module has its own input capacitor and that the output voltages are matched within 1%.
