RO-1209S - RECOM Power

RO-1209S 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 2 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 derating the output power of the module according to the temperature derating curve provided in the datasheet. Additionally, ensuring good airflow and heat dissipation around the module is crucial.
• What is the recommended input capacitor type and value for this module?
  RECOM recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, rated for the input voltage of the module. This helps to filter out input noise and ensure stable operation.
• Can I use this module in a redundant or parallel configuration?
  Yes, the RO-1209S can be used in a redundant or parallel configuration, but RECOM recommends consulting with their application engineers to ensure proper design and implementation. Additionally, the modules should be synchronized to prevent oscillations and ensure stable operation.
• What is the typical MTBF (Mean Time Between Failures) of this module?
  According to RECOM, the typical MTBF of the RO-1209S is >1.5 million hours, calculated according to MIL-HDBK-217F at 40°C ambient temperature and 50% load.
