RAC03-3.3SK Frequently Asked Questions (FAQs)

  • 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 solid ground plane to reduce thermal resistance.
  • Yes, the RAC03-3.3SK is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in industrial and transportation applications. However, it's essential to ensure proper PCB mounting and screw torque to prevent damage.
  • Use a suitable input voltage regulator or a voltage stabilizer to ensure the input voltage stays within the recommended range of 36-75V DC. This will prevent damage to the module and ensure reliable operation.
  • RECOM recommends using a low-ESR capacitor with a value of 10-22uF, X7R or X5R type, and a voltage rating of 50-100V DC. This will help reduce input ripple and ensure stable operation.
  • Yes, you can parallel multiple RAC03-3.3SK modules to increase the output current. However, it's essential to ensure that each module has its own input capacitor and that the modules are connected in parallel correctly to prevent current imbalance and reduce the risk of oscillation.
