RO-3.312S - RECOM Power

RO-3.312S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 1 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
• How do I ensure the module's reliability in high-temperature environments?
  To ensure reliability in high-temperature environments, RECOM recommends following the derating curves provided in the datasheet. Additionally, the module should be mounted on a heat sink or a metal plate to dissipate heat, and the ambient temperature should be kept below the maximum rated temperature of 85°C.
• What is the recommended input capacitor type and value for this module?
  RECOM recommends using a low-ESR ceramic capacitor with a value of 10-22 μF and a voltage rating of 50-100 V. The capacitor should be placed as close as possible to the module's input pins to minimize noise and ripple.
• Can I use this module in a redundant or parallel configuration?
  Yes, the RO-3.312S can be used in a redundant or parallel configuration to achieve higher power ratings or to improve system reliability. However, RECOM recommends consulting with their application engineers to ensure proper design and implementation of the redundant or parallel configuration.
• What is the typical MTBF (Mean Time Between Failures) of this module?
  The typical MTBF of the RO-3.312S is >1 million hours, calculated according to MIL-HDBK-217F. However, the actual MTBF may vary depending on the operating conditions and environment.
