PDME2-S24-S5-S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, ensure good airflow around the module and consider adding a heat sink if operating in high-temperature environments.
• How do I ensure electromagnetic compatibility (EMC) with this module?
  To ensure EMC, CUI recommends following proper PCB design and layout guidelines, using a metal enclosure, and adding EMI filters or shielding if necessary. Additionally, ensure that the module is properly grounded and that all cables are properly shielded and terminated.
• What is the maximum allowable ripple current for the input capacitors?
  CUI recommends limiting the input capacitor ripple current to 20% of the rated current to ensure reliable operation and minimize component stress.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PDME2-S24-S5-S can be used in redundant or parallel configurations, but CUI recommends consulting with their application engineers to ensure proper design and implementation to avoid any potential issues.
• What is the typical MTBF (mean time between failures) for this module?
  CUI estimates the MTBF for the PDME2-S24-S5-S to be around 1.5 million hours, based on MIL-HDBK-217F calculations. However, actual MTBF may vary depending on operating conditions and environmental factors.
