SWI3-5-N-P5 - CUI Inc.

SWI3-5-N-P5 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 a minimum of 1mm clearance around the module to allow for airflow.
• How do I ensure electromagnetic compatibility (EMC) with the SWI3-5-N-P5?
  To ensure EMC, CUI recommends following proper PCB design and layout guidelines, using a metal enclosure, and implementing EMI filtering on the input and output lines. Additionally, the module should be installed in a way that minimizes radiation and conduction of electromagnetic interference.
• What is the derating curve for the SWI3-5-N-P5 at high temperatures?
  CUI provides a derating curve in the datasheet, but for more detailed information, engineers can contact CUI's technical support team for a customized derating curve based on their specific application and environmental conditions.
• Can I use the SWI3-5-N-P5 in a redundant or parallel configuration?
  Yes, the SWI3-5-N-P5 can be used in a redundant or parallel configuration, but it requires careful design and implementation to ensure proper operation and fault tolerance. Engineers should consult with CUI's technical support team for guidance on specific implementation details.
• What is the MTBF (Mean Time Between Failures) of the SWI3-5-N-P5?
  CUI provides an MTBF rating of >1 million hours at 25°C and 50% load, calculated according to MIL-HDBK-217F. However, actual MTBF may vary depending on the application, environment, and operating conditions.
