VHB75W-Q24-S24 - CUI Inc.

VHB75W-Q24-S24 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI Inc recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
• How do I ensure reliable operation in high-vibration environments?
  CUI Inc recommends securing the module with screws or adhesive, and using a vibration-dampening material to reduce mechanical stress. Additionally, ensure that the PCB is designed to withstand vibrations and that the module is properly soldered.
• What is the maximum allowable capacitance for the input and output filters?
  CUI Inc recommends following the guidelines in the datasheet for input and output filter capacitance. Exceeding the recommended capacitance values may affect the module's stability and performance.
• Can I use this module in a redundant or parallel configuration?
  Yes, the VHB75W-Q24-S24 can be used in redundant or parallel configurations, but it's essential to follow CUI Inc's guidelines for synchronization and current sharing to ensure reliable operation.
• What is the typical MTBF (Mean Time Between Failures) for this module?
  CUI Inc provides an MTBF of 1.5 million hours at 25°C, calculated according to MIL-HDBK-217F. However, the actual MTBF may vary depending on the application, environment, and operating conditions.
