FMMT491A Frequently Asked Questions (FAQs)

  • A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • The FMMT491A requires a bias voltage of 5V to 15V. Ensure the input voltage is within this range and the output is properly terminated to avoid oscillations.
  • The maximum power dissipation of the FMMT491A is 1.5W. Ensure the device is properly heat-sinked and the ambient temperature is within the recommended range to avoid overheating.
  • Yes, the FMMT491A can be used in switching regulator applications. However, ensure the device is properly biased and the output is properly filtered to avoid oscillations.
  • The recommended storage temperature range for the FMMT491A is -40°C to 125°C. Storing the device outside this range may affect its reliability and performance.
