PTD902-2020K-B103 - Bourns

PTD902-2020K-B103 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Bourns recommends a symmetrical PCB layout with a solid ground plane to minimize electromagnetic interference (EMI) and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
• How do I handle the thermal considerations for this transformer?
  The PTD902-2020K-B103 has a maximum ambient operating temperature of 40°C. Ensure good airflow around the transformer and consider heat sinking or thermal interface materials if operating in high-temperature environments.
• What is the recommended creepage and clearance distance for this transformer?
  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 safety and meet regulatory requirements.
• Can I use this transformer in a high-vibration environment?
  The PTD902-2020K-B103 is designed to withstand moderate vibration levels. However, if your application involves extreme vibration, consider using additional mechanical support or vibration-dampening materials to ensure reliability.
• How do I ensure electromagnetic compatibility (EMC) with this transformer?
  Use shielding, filtering, and grounding techniques to minimize electromagnetic radiation and susceptibility. Ensure that the transformer is properly grounded and consider using a metal shield or screen to contain EMI.
