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

  • CUI recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
  • CUI recommends using a soldering iron with a temperature range of 250°C to 270°C, and applying a small amount of solder paste to the pads before reflow soldering.
  • The PEM1-S3-S5-S is rated for operation from -40°C to 85°C, but derating is required for temperatures above 70°C to ensure reliable operation.
  • Yes, the PEM1-S3-S5-S is designed to withstand vibrations up to 10G, but it's recommended to secure the module to the PCB using screws or adhesive to ensure reliable operation.
  • CUI recommends checking the input voltage, output voltage, and current draw to identify the source of the issue. Consult the datasheet and application notes for troubleshooting guidelines.
