PCN1-S12-S15-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 1 oz copper thickness is recommended. Additionally, a thermal interface material (TIM) can be used to improve heat transfer between the device and the heat sink.
• How do I ensure reliable operation in high-vibration environments?
  CUI recommends following the recommended PCB mounting and screw torque specifications to ensure the device is securely fastened. Additionally, using a conformal coating and potting the device can help improve reliability in high-vibration environments.
• What is the maximum allowable voltage derating for this device?
  CUI recommends derating the input voltage by 10% to ensure reliable operation and to account for any voltage spikes or transients. This will help prevent damage to the device and ensure long-term reliability.
• Can I use this device in a redundant or parallel configuration?
  Yes, the PCN1-S12-S15-S can be used in a redundant or parallel configuration to improve system reliability and availability. However, it is essential to follow CUI's guidelines for paralleling and redundancy to ensure proper operation and to avoid any potential issues.
• What is the typical MTBF (Mean Time Between Failures) for this device?
  CUI provides an MTBF rating of 1.5 million hours at 25°C, calculated according to MIL-HDBK-217F. However, this rating may vary depending on the specific application and operating conditions.
