1641R-223K Frequently Asked Questions (FAQs)

  • API Delevan recommends a pad layout with a minimum of 0.05 inches (1.27 mm) of clearance around the inductor body to ensure proper thermal performance and to prevent electrical shorts.
  • While the 1641R-223K is rated for operation up to 125°C, API Delevan recommends derating the inductor's current rating by 1.5% for every degree above 80°C to ensure reliable operation and prevent thermal runaway.
  • To minimize magnetic field interference, API Delevan suggests keeping a minimum of 0.1 inches (2.54 mm) of clearance between the 1641R-223K and other magnetic components, and orienting the inductor to minimize flux lines intersecting with nearby components.
  • API Delevan does not provide a specific SRF value for the 1641R-223K, but recommends using a frequency-dependent impedance model or consulting with their application engineers to determine the SRF for a specific application.
  • While the 1641R-223K is designed to withstand moderate vibration, API Delevan recommends consulting with their application engineers to determine the suitability of the inductor for high-vibration applications, and to discuss potential custom designs or modifications.
