1641R-102K - API Delevan

1641R-102K Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 1641R-102K?
  The recommended PCB land pattern for the 1641R-102K can be found in the API Delevan application note AN-113, which provides detailed guidelines for PCB layout and footprint design.
• How does the 1641R-102K 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 1641R-102K suitable for use in high-reliability or military applications?
  Yes, the 1641R-102K is designed to meet the requirements of MIL-PRF-83446 and is suitable for use in high-reliability and military applications. However, it's essential to consult with API Delevan's sales team to discuss specific requirements and obtain the necessary certifications.
• Can the 1641R-102K be used in applications with high-voltage spikes or surges?
  While the 1641R-102K has a rated voltage of 100V, it can withstand voltage spikes up to 150V for short durations (less than 1ms). However, it's crucial to ensure that the inductor is properly sized and designed to handle the expected voltage transients in the application.
• How does the 1641R-102K behave in parallel or series configurations?
  API Delevan recommends following the guidelines outlined in their application note AN-114 for parallel and series configurations of the 1641R-102K. This includes ensuring that the inductors are properly matched and that the PCB layout is designed to minimize parasitic effects.
