SDM65-15-U-P5 - CUI Inc.

SDM65-15-U-P5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI Inc 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.
• How do I ensure reliable operation in high-vibration environments?
  To ensure reliable operation in high-vibration environments, CUI Inc recommends securing the module to the PCB using screws or adhesive, and using a conformal coating to protect the module from moisture and contaminants. Additionally, the module should be mounted in a way that minimizes stress on the connectors and wires.
• What is the maximum allowable capacitance for the output filter?
  The maximum allowable capacitance for the output filter is 10uF. Exceeding this value may cause instability or oscillation in the output voltage.
• Can I use this module in a redundant or parallel configuration?
  Yes, the SDM65-15-U-P5 can be used in a redundant or parallel configuration, but it requires careful design and implementation to ensure proper operation and fault tolerance. CUI Inc recommends consulting with their application engineers for guidance on implementing such configurations.
• What is the typical MTBF (Mean Time Between Failures) for this module?
  The typical MTBF for the SDM65-15-U-P5 is >1 million hours, calculated according to MIL-HDBK-217F. However, this value may vary depending on the specific application, operating conditions, and environmental factors.
