CQHS2504832 Frequently Asked Questions (FAQs)

  • Cosel 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.
  • To ensure EMC, Cosel recommends following the guidelines in the datasheet for input and output filtering, and using a metal enclosure with proper shielding and grounding to minimize electromagnetic interference.
  • Cosel provides a derating curve in the datasheet, which shows the maximum output power vs. altitude. For example, at 10,000 feet, the output power is derated by 10%.
  • Yes, the CQHS2504832 can be used in a redundant configuration, but it requires a specific setup and synchronization of the power supplies to ensure seamless switchover in case of a failure. Consult Cosel's application notes for more information.
  • The MTBF of the CQHS2504832 is calculated according to the Telcordia SR-332 standard, and it is typically in the range of 500,000 to 1,000,000 hours, depending on the operating conditions and environment.
