RI3-1205S - RECOM Power

RI3-1205S 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.
• Can I use the RI3-1205S in a high-vibration environment?
  Yes, the RI3-1205S is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in industrial and transportation applications. However, it's recommended to follow proper mounting and screwing procedures to ensure the module is securely fastened to the PCB or chassis.
• How do I ensure the module's input voltage stays within the recommended range?
  RECOM recommends using a voltage regulator or a DC-DC converter to regulate the input voltage to the RI3-1205S. Additionally, a voltage monitoring circuit can be implemented to detect and respond to input voltage deviations.
• What is the recommended input capacitance for the RI3-1205S?
  RECOM recommends using a minimum of 10uF input capacitance to ensure stable operation and to reduce input voltage ripple. The input capacitance should be placed as close as possible to the module's input pins.
• Can I use the RI3-1205S in a high-temperature environment?
  The RI3-1205S is rated for operation up to 85°C ambient temperature. However, derating may be necessary for temperatures above 70°C. RECOM recommends consulting the datasheet and application notes for specific guidance on thermal derating and heat management.
