PDQE10-Q24-S3-U Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI Inc recommends a PCB layout with a minimum of 2 oz copper thickness, a 1-inch square copper pad under the module, and a 1-inch wide copper trace connecting the pad to the input capacitors to ensure optimal thermal performance.
• Can I use this module in a high-vibration environment?
  Yes, the PDQE10-Q24-S3-U is designed to withstand high-vibration environments. It meets the IEC 60068-2-6 vibration test standard, which involves sinusoidal vibration at 10-2000 Hz, 2 G peak acceleration, and 1-hour duration.
• How do I ensure electromagnetic compatibility (EMC) with this module?
  To ensure EMC, CUI Inc recommends using a metal enclosure, keeping the module at least 1 cm away from other components, and using a common-mode choke or ferrite bead on the input lines. Additionally, the module's output should be decoupled with a capacitor and a ferrite bead.
• What is the maximum allowable capacitance for the output filter capacitor?
  The maximum allowable capacitance for the output filter capacitor is 1000 μF. Exceeding this value may cause instability or oscillation in the module.
• Can I use this module in a high-altitude environment?
  Yes, the PDQE10-Q24-S3-U is designed to operate up to 5000 meters (16,400 feet) above sea level. However, the module's power rating may need to be derated at higher altitudes due to the lower air pressure and cooling efficiency.
