SM91076L-E Frequently Asked Questions (FAQs)

  • Bourns recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a microstrip or stripline layout for the high-frequency signals. A minimum of 50 mil clearance around the device is recommended to ensure proper heat dissipation.
  • Use a soldering iron with a fine tip and a temperature of 250°C to 270°C. Apply a small amount of solder paste to the pads, and use a gentle touch to avoid applying excessive pressure. Inspect the solder joints under a microscope to ensure they are clean and free of bridging.
  • The SM91076L-E is rated for operation from -40°C to +125°C, but it's recommended to derate the device by 1.5°C/W above 85°C to ensure reliable operation.
  • Yes, the SM91076L-E is designed to withstand vibrations up to 10 G peak acceleration, but it's recommended to follow proper PCB mounting and screwing procedures to ensure the device remains securely attached.
  • Check the input voltage and current, ensure proper PCB layout and decoupling, and verify the output voltage and current are within the specified ranges. Use an oscilloscope to monitor the output voltage and current waveforms, and consult the datasheet and application notes for troubleshooting guidelines.
