RAC3.5-3.3SK/277 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 1 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
  • Yes, the RAC3.5-3.3SK/277 is designed to withstand high-vibration environments. However, it's recommended to follow the recommended PCB layout and mounting guidelines to ensure the module is securely attached to the PCB and can withstand the vibrations.
  • The maximum allowed capacitance load for the output is 2200uF. Exceeding this value may cause instability or oscillation in the output voltage.
  • Yes, the RAC3.5-3.3SK/277 can be used in a redundant configuration. However, it's recommended to follow the recommended layout and connection guidelines to ensure proper operation and to prevent any potential issues.
  • The typical efficiency of the RAC3.5-3.3SK/277 is around 85-90% depending on the input voltage and output load. Please refer to the datasheet for more detailed efficiency curves.
