1641R-474K Frequently Asked Questions (FAQs)

  • The recommended land pattern for the 1641R-474K can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and land pattern design.
  • 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.
  • Yes, the 1641R-474K is designed to meet the requirements of high-reliability and military applications. API Delevan offers a range of screening options, including MIL-PRF-83446, to ensure the inductor meets the necessary standards for these applications.
  • While the 1641R-474K is primarily designed for use in DC-DC converters and power supplies, it can be used in high-frequency applications up to 1 MHz. However, the inductor's performance may degrade at higher frequencies, and API Delevan recommends consulting with their application engineers for specific guidance.
  • The lead time and minimum order quantity for the 1641R-474K vary depending on the specific requirements and availability. Engineers should contact API Delevan's sales team or authorized distributors for the most up-to-date information and to discuss their specific needs.
