4590R-105K Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 4590R-105K?
  The recommended PCB land pattern for the 4590R-105K can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and footprint design.
• How does the 4590R-105K 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.
• Is the 4590R-105K suitable for use in high-reliability or safety-critical applications?
  Yes, the 4590R-105K is designed and manufactured to meet the requirements of high-reliability and safety-critical applications, such as aerospace, defense, and medical devices. However, it is essential to consult with API Delevan's application engineers to ensure the inductor meets the specific requirements of the application.
• Can the 4590R-105K be used in high-frequency applications above 1 MHz?
  While the datasheet specifies a maximum frequency of 1 MHz, the 4590R-105K can be used in high-frequency applications up to 5 MHz with proper impedance matching and PCB design. However, it is recommended to consult with API Delevan's application engineers to ensure the inductor's performance meets the specific requirements of the application.
• What is the recommended storage and handling procedure for the 4590R-105K?
  API Delevan recommends storing the 4590R-105K in a dry, cool place, away from direct sunlight and moisture. The inductors should be handled with care to avoid mechanical stress, and electrostatic discharge (ESD) precautions should be taken during handling and assembly.
