CW201212-R47J - Bourns

CW201212-R47J Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns recommends a symmetrical layout with a 1:1 aspect ratio for the pads, and a minimum of 0.5 mm clearance between the component and other components or copper features. A detailed land pattern is available in the Bourns application note AN-13.
• How does the CW201212-R47J perform in high-temperature environments?
  The CW201212-R47J is rated for operation up to 150°C, but its performance may degrade above 125°C. For high-temperature applications, consider using a thermally conductive pad and ensuring good airflow to minimize thermal resistance.
• What is the recommended soldering profile for the CW201212-R47J?
  Bourns recommends a soldering profile with a peak temperature of 240°C, a dwell time of 30-60 seconds, and a cooling rate of 4°C/s. Avoid using excessive soldering temperatures or times to prevent damage to the component.
• Can the CW201212-R47J be used in high-vibration or high-shock environments?
  Yes, the CW201212-R47J is designed to withstand moderate vibration and shock. However, for extreme environments, consider using additional mechanical support or potting the component to ensure reliability.
• How does the CW201212-R47J behave in high-frequency applications?
  The CW201212-R47J is designed for low-frequency applications. For high-frequency applications, consider using a different component or consulting with a Bourns application engineer to determine the best solution.
