SRU1028-8R2Y - Bourns

SRU1028-8R2Y Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize parasitic inductance and capacitance.
• How do I ensure reliable operation in high-temperature environments?
  Bourns recommends derating the current rating of the SRU1028-8R2Y by 1.5% per degree Celsius above 40°C, and ensuring good airflow and heat sinking to keep the device within its operating temperature range.
• What is the maximum allowable voltage stress on the input and output pins?
  The SRU1028-8R2Y can withstand voltage stress up to 1.5 times the rated voltage for a maximum of 100ms, but prolonged exposure to high voltage stress can reduce the device's lifespan.
• How do I troubleshoot common issues such as output voltage sag or oscillation?
  Check for proper PCB layout, ensure adequate input and output decoupling, and verify that the input voltage is within the recommended range. Also, check for any signs of overheating or physical damage to the device.
• Is the SRU1028-8R2Y compatible with lead-free soldering processes?
  Yes, the SRU1028-8R2Y is compatible with lead-free soldering processes, but Bourns recommends following the recommended soldering profile to ensure reliable operation.
