1641-394K Frequently Asked Questions (FAQs)

  • The recommended PCB land pattern for the 1641-394K is a rectangular pad with a minimum size of 0.25 inches (6.4 mm) x 0.15 inches (3.8 mm) and a maximum size of 0.35 inches (8.9 mm) x 0.25 inches (6.4 mm).
  • The 1641-394K is rated for operation up to 125°C, but it's recommended to derate the current rating by 1.5% per degree Celsius above 80°C to ensure reliable operation.
  • The 1641-394K is designed for high-frequency applications up to 1 GHz. However, it's essential to consider the self-resonant frequency (SRF) of the inductor, which is around 150 MHz, to avoid unwanted resonances.
  • The 1641-394K has a maximum current rating of 3.9 A, but it's recommended to consider the inductor's temperature rise and derate the current accordingly to ensure reliable operation.
  • Yes, the 1641-394K is suitable for switching regulator applications due to its low core loss and high saturation current rating. However, it's essential to consider the inductor's core material and design to minimize core losses and ensure efficient operation.
