PDQ10-Q48-D12-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  CUI Inc recommends a PCB layout with a solid ground plane, minimal trace length, and a decoupling capacitor (e.g., 10uF) between the input and output pins to ensure stable operation and minimize EMI.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, CUI Inc recommends derating the output power by 2.5% per degree Celsius above 40°C, and ensuring good airflow around the device. Additionally, consider using a heat sink or thermal interface material to reduce the junction temperature.
• What is the maximum cable length for the input and output connections?
  CUI Inc recommends keeping the input and output cable lengths as short as possible (less than 10 inches) to minimize voltage drops and ensure reliable operation. If longer cables are necessary, consider using twisted pair or shielded cables to reduce EMI and noise.
• Can I use this DC-DC converter in a redundant or parallel configuration?
  Yes, the PDQ10-Q48-D12-D can be used in a redundant or parallel configuration, but CUI Inc recommends consulting with their application engineers to ensure proper design and implementation to avoid any potential issues or instability.
• What is the typical MTBF (Mean Time Between Failures) for this device?
  CUI Inc reports a typical MTBF of 1.5 million hours for the PDQ10-Q48-D12-D, calculated according to MIL-HDBK-217F, Notice 2. However, actual MTBF may vary depending on the application, operating conditions, and other factors.
