1641R-273K Frequently Asked Questions (FAQs)

  • The recommended land pattern for the 1641R-273K can be found in the API Delevan application note AN-013, which provides detailed guidelines for PCB layout and footprint 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-273K 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.
  • The SRF of the 1641R-273K is approximately 250 MHz, which is not explicitly stated in the datasheet. This information can be obtained by contacting API Delevan's technical support or through application notes.
  • Yes, the 1641R-273K 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 to prevent damage to the inductor.
