PF-ET1-15 - Bourns

PF-ET1-15 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the PF-ET1-15?
  Bourns recommends a symmetrical PCB layout with the transformer centered on the board, and the primary and secondary windings on opposite sides of the board to minimize electromagnetic interference (EMI).
• How do I ensure the PF-ET1-15 operates within its specified temperature range?
  Ensure good airflow around the transformer, avoid blocking the airflow vents, and consider using a heat sink or thermal interface material if the operating temperature is expected to exceed 85°C.
• What is the recommended creepage and clearance distance for the PF-ET1-15?
  Bourns recommends a minimum creepage distance of 2.5 mm and a minimum clearance distance of 2 mm between the primary and secondary windings to ensure safe operation and meet regulatory requirements.
• Can I use the PF-ET1-15 in a high-vibration environment?
  Yes, the PF-ET1-15 is designed to withstand vibrations up to 10 G peak acceleration, but it's recommended to secure the transformer to the PCB using a suitable adhesive or mechanical fastening to prevent movement and ensure reliable operation.
• How do I troubleshoot common issues with the PF-ET1-15, such as overheating or low output voltage?
  Check the input voltage, current, and frequency; ensure proper PCB layout and thermal management; verify the transformer is properly secured to the PCB; and consult the Bourns application notes and technical support resources for guidance.
