PEM1-S5-S3-S Frequently Asked Questions (FAQs)

  • A thermal pad on the bottom of the module should be connected to a large copper area on the PCB to dissipate heat. A minimum of 2 oz copper thickness is recommended.
  • Ensure a soft-start circuit is implemented to limit inrush current. A NTC thermistor in series with the input capacitor can help reduce inrush current.
  • The maximum allowable capacitance is 220uF. Exceeding this value may cause instability or oscillation.
  • Yes, but ensure the module is securely fastened to the PCB and the PCB is properly secured to the chassis to prevent damage from vibration.
  • Check the input voltage, output load, and ambient temperature. Verify the module is properly soldered and the PCB layout is correct. Consult the datasheet for troubleshooting guidelines.
