PQMC3-D5-D15-S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A recommended PCB layout is to keep the input and output capacitors close to the module, and to use a solid ground plane to reduce noise and EMI. Additionally, it's recommended to keep the input and output traces separate to minimize cross-talk.
• How do I ensure the module is properly cooled?
  The module should be mounted on a heat sink or a metal plate to ensure proper heat dissipation. The heat sink should be designed to provide adequate airflow and thermal conductivity. It's also recommended to keep the module away from any obstructions that may block airflow.
• What is the maximum allowable input voltage deviation?
  The maximum allowable input voltage deviation is ±10% of the nominal input voltage. Exceeding this deviation may affect the module's performance and reliability.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PQMC3-D5-D15-S can be used in a redundant or parallel configuration to achieve higher power output or redundancy. However, it's recommended to consult with CUI Inc's application engineers to ensure proper design and implementation.
• What is the typical MTBF (Mean Time Between Failures) of this module?
  The typical MTBF of the PQMC3-D5-D15-S is >1 million hours, calculated according to MIL-HDBK-217F. However, this value may vary depending on the operating conditions and environment.
