R-543.3PA Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 2 oz copper thickness is recommended.
  • Yes, the R-543.3PA is designed to withstand high vibrations. However, it's essential to follow the recommended PCB mounting and screw torque guidelines to ensure the module remains securely attached.
  • RECOM recommends adding external input filtering components, such as a common-mode choke and X-capacitors, to meet specific EMC requirements. Consult the datasheet and RECOM's application notes for guidance.
  • The maximum allowed capacitance on the output is 2200 μF. Exceeding this value may affect the module's stability and performance.
  • Yes, you can parallel multiple R-543.3PA modules to increase the output power. However, it's crucial to ensure proper synchronization and current sharing between the modules. Consult RECOM's application notes for guidance.
