PYBE20-Q48-S24 Frequently Asked Questions (FAQs)

  • 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, a thermal interface material (TIM) with a thermal conductivity of 1-2 W/m-K should be used between the module and the heat sink.
  • CUI recommends following the recommended PCB mounting and screw torque specifications to ensure the module is securely fastened. Additionally, using a conformal coating and potting the module can help improve reliability in high-vibration environments.
  • CUI recommends operating the module within ±10% of the nominal 48V input voltage to ensure reliable operation and to prevent damage to the module.
  • Yes, the PYBE20-Q48-S24 is designed to be used in redundant or N+1 configurations. However, it's essential to follow CUI's guidelines for paralleling and redundancy to ensure reliable operation and to prevent damage to the modules.
  • CUI estimates the MTBF for the PYBE20-Q48-S24 to be around 1.5 million hours, based on MIL-HDBK-217F calculations. However, this value may vary depending on the specific application and operating conditions.
