4922R-49L - API Delevan

4922R-49L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 4922R-49L?
  The recommended land pattern for the 4922R-49L can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and land pattern design.
• How do I handle the 4922R-49L's sensitivity to temperature?
  The 4922R-49L's inductance value can vary with temperature. To minimize the impact of temperature on the inductor's performance, it's recommended to use a thermally stable PCB material, ensure good airflow around the component, and consider using a temperature-compensating circuit design.
• Can I use the 4922R-49L in a high-frequency application?
  While the 4922R-49L is designed for high-frequency applications, its performance may degrade above 100 MHz. For frequencies above 100 MHz, it's recommended to consult with API Delevan's application engineers to determine the best inductor for the specific application.
• How do I ensure the 4922R-49L meets my specific impedance requirements?
  The 4922R-49L's impedance characteristics can be affected by the PCB layout, nearby components, and operating frequency. To ensure the inductor meets specific impedance requirements, it's recommended to perform impedance measurements and simulations using tools like SPICE or ANSYS, and consult with API Delevan's application engineers if necessary.
• What is the maximum current rating for the 4922R-49L?
  The maximum current rating for the 4922R-49L is not explicitly stated in the datasheet. However, the inductor's current handling capability can be determined by consulting API Delevan's application note AN-012, which provides guidelines for calculating the maximum current rating based on the inductor's physical characteristics and operating conditions.
