VMS-20-3.3 Frequently Asked Questions (FAQs)

  • CUI recommends a PCB layout with a large copper area underneath the module to dissipate heat effectively. A minimum of 2 oz copper thickness is recommended, and the use of thermal vias can further improve heat dissipation.
  • CUI recommends using a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 180°C to 190°C. Apply a small amount of solder to the pins and ensure a smooth, even solder joint.
  • The maximum capacitance load for the output of the VMS-20-3.3 is 10,000 μF. Exceeding this value may cause instability or oscillation in the output voltage.
  • Yes, the VMS-20-3.3 is designed to withstand high-vibration environments. However, it's essential to ensure the module is properly secured to the PCB and the PCB is securely fastened to the system to prevent damage or dislodging.
  • The typical efficiency of the VMS-20-3.3 is around 85% to 90% depending on the input voltage and output load. Refer to the datasheet for detailed efficiency curves.
