WRA1205S-1WR2 Frequently Asked Questions (FAQs)

  • MORNSUN recommends a PCB layout with a large copper area connected to the GND pin to dissipate heat effectively. A minimum of 1 oz copper thickness is recommended.
  • Yes, the WRA1205S-1WR2 is designed to withstand vibrations up to 10G (10-2000Hz) and can be used in high-vibration environments with proper mounting and PCB design.
  • MORNSUN provides a derating curve in the application note, which shows that the output current should be derated by 2.5% per degree Celsius above 40°C to ensure reliable operation.
  • Yes, the WRA1205S-1WR2 is designed to operate in humid environments with a relative humidity up to 95% (non-condensing). However, it's recommended to apply a conformal coating to protect the device from moisture.
  • MORNSUN recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, X7R or X5R dielectric, and a voltage rating of 25V or higher.
