1641-224K - API Delevan

1641-224K Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the 1641-224K?
  The recommended PCB land pattern for the 1641-224K can be found in the API Delevan application note AN-113, which provides detailed guidelines for PCB layout and footprint design.
• How does the 1641-224K 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 1641-224K be used in high-vibration applications?
  Yes, the 1641-224K 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 (SRF) of the 1641-224K?
  The SRF of the 1641-224K is approximately 150 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.
• Is the 1641-224K compatible with lead-free soldering processes?
  Yes, the 1641-224K is compatible with lead-free soldering processes, including SAC305 and Sn96.5Ag3Cu0.5. However, it's essential to follow the recommended soldering profile and temperature guidelines to ensure reliable assembly.
