4922R-26L - API Delevan

4922R-26L Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 4922R-26L?
  The recommended PCB land pattern for the 4922R-26L can be found in the API Delevan application note AN-001, which provides a detailed layout and footprint recommendation for optimal performance and reliability.
• How does the 4922R-26L perform in high-temperature environments?
  The 4922R-26L is rated for operation up to 125°C, but its performance may degrade at higher temperatures. API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
• Is the 4922R-26L compatible with lead-free soldering processes?
  Yes, the 4922R-26L is compatible with lead-free soldering processes and meets the requirements of the RoHS directive. However, API Delevan recommends following their recommended soldering profile to ensure optimal reliability.
• What is the self-resonant frequency (SRF) of the 4922R-26L?
  The self-resonant frequency (SRF) of the 4922R-26L is not explicitly stated in the datasheet, but it can be estimated to be around 150-200 MHz based on the inductor's physical characteristics and materials. However, this value may vary depending on the specific application and PCB layout.
• Can the 4922R-26L be used in high-reliability or military applications?
  The 4922R-26L is a commercial-grade inductor, but API Delevan offers a range of high-reliability and military-grade inductors that meet the requirements of MIL-PRF-83446 and other relevant standards. Engineers should contact API Delevan directly to discuss their specific requirements and determine the most suitable product.
