SM91072AL-E - Bourns

SM91072AL-E 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 device's current rating according to the temperature derating curve provided in the datasheet, and ensuring good thermal management through proper heat sinking and airflow.
• What is the maximum allowable voltage stress on the device?
  The SM91072AL-E is designed to withstand voltage stresses up to 1.5 times the rated voltage for a short duration (typically 100 ms). However, it's recommended to follow the recommended operating conditions to ensure reliable operation.
• Can I use this device in a high-frequency application?
  While the SM91072AL-E is designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with proper PCB layout and component selection. However, it's essential to evaluate the device's performance and stability in the specific application.
• How do I troubleshoot common issues like overheating or malfunction?
  Bourns recommends following a systematic troubleshooting approach, including checking the device's operating conditions, PCB layout, and component selection. Additionally, consulting the datasheet and application notes can provide valuable insights into potential issues and solutions.
