4590R-823K - API Delevan

4590R-823K Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 4590R-823K?
  The recommended land pattern for the 4590R-823K can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and land pattern design.
• How does the 4590R-823K 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 4590R-823K be used in high-vibration applications?
  Yes, the 4590R-823K is designed to withstand vibrations up to 10g peak acceleration, making it suitable for use in high-vibration environments. However, it's essential to ensure proper PCB mounting and secure the inductor to prevent mechanical stress.
• What is the self-resonant frequency of the 4590R-823K?
  The self-resonant frequency of the 4590R-823K is typically around 150-200 MHz, but this can vary depending on the specific application and PCB layout. It's recommended to perform simulations or measurements to determine the self-resonant frequency in your specific design.
• Is the 4590R-823K compatible with lead-free soldering processes?
  Yes, the 4590R-823K is compatible with lead-free soldering processes, with a peak reflow temperature of 260°C. However, it's essential to follow the recommended soldering profile and ensure that the inductor is properly cleaned and dried before soldering.
