TUHS15F12 - Cosel

TUHS15F12 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Cosel recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat transfer.
• How do I ensure reliable start-up and shutdown of the TUHS15F12?
  To ensure reliable start-up and shutdown, Cosel recommends a soft-start circuit to limit inrush current, and a shutdown circuit with a minimum of 10ms delay to prevent voltage spikes.
• What are the derating curves for the TUHS15F12 at high temperatures?
  Cosel provides derating curves in the datasheet, but for specific high-temperature applications, engineers can contact Cosel's technical support for customized derating curves based on their specific use case.
• Can I use the TUHS15F12 in a redundant configuration for high-reliability applications?
  Yes, the TUHS15F12 can be used in a redundant configuration, but engineers should ensure that the redundant modules are properly synchronized and that the system is designed to handle the increased power consumption.
• What are the EMI filter requirements for the TUHS15F12?
  Cosel recommends using a CISPR 11 Class B EMI filter with a minimum of 30dB attenuation at 150kHz to ensure compliance with electromagnetic interference regulations.
