PRM3W-E12-D5-S Frequently Asked Questions (FAQs)

  • CUI Inc recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2 oz copper thickness. A thermal via array under the module can also improve heat transfer.
  • CUI Inc recommends using a soldering profile with a peak temperature of 240°C to 250°C, and a dwell time of 30 seconds to 60 seconds. Avoid using excessive soldering temperature or time to prevent damage to the module.
  • The PRM3W-E12-D5-S can tolerate an input voltage deviation of ±10% of the nominal input voltage without affecting its performance or reliability.
  • CUI Inc recommends using external overcurrent protection (OCP) and overvoltage protection (OVP) circuits to prevent damage to the module. The OCP should be set to 150% of the maximum rated output current, and the OVP should be set to 120% of the maximum rated output voltage.
  • The typical efficiency of the PRM3W-E12-D5-S is around 85% to 90% depending on the input voltage and output load conditions.
