4922R-271L - API Delevan

4922R-271L Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 4922R-271L?
  The recommended PCB land pattern for the 4922R-271L can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and design.
• How does the 4922R-271L perform in high-temperature environments?
  While the datasheet specifies an operating temperature range of -40°C to +125°C, API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation in high-temperature environments.
• Can the 4922R-271L be used in high-frequency applications?
  Yes, the 4922R-271L is designed for high-frequency applications up to 1 GHz. However, it's essential to consider the inductor's self-resonant frequency (SRF) and ensure that the operating frequency is below the SRF to avoid unwanted resonances.
• What is the maximum allowable voltage for the 4922R-271L?
  The maximum allowable voltage for the 4922R-271L is 50 Vrms. Exceeding this voltage may result in reduced reliability or even damage to the inductor.
• How do I ensure the 4922R-271L meets my specific application's requirements for electromagnetic interference (EMI)?
  To minimize EMI, API Delevan recommends using the 4922R-271L in conjunction with proper PCB layout techniques, such as using ground planes, shielding, and minimizing loop areas. Additionally, consider using EMI filters or common-mode chokes in conjunction with the inductor.
