VCD30-D12-S5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI 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 dissipation.
• How do I ensure reliable soldering of the module?
  CUI 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.
• What is the maximum allowable voltage derating for this module?
  CUI recommends derating the input voltage by 10% to 15% to ensure reliable operation and to prevent overvoltage stress on the module.
• Can I use this module in a high-humidity environment?
  The VCD30-D12-S5 is designed to operate in a humidity range of 20% to 80% RH. However, CUI recommends taking precautions to prevent moisture ingress, such as conformal coating or potting, for applications in high-humidity environments.
• What is the typical MTBF (Mean Time Between Failures) for this module?
  CUI estimates the MTBF of the VCD30-D12-S5 to be around 1.5 million hours, based on MIL-HDBK-217F calculations. However, actual MTBF may vary depending on the application and operating conditions.
