1025-18K Frequently Asked Questions (FAQs)

  • The recommended PCB land pattern for the 1025-18K is a rectangular pad with a minimum size of 0.125 inches (3.18 mm) x 0.25 inches (6.35 mm) with a 0.05 inches (1.27 mm) spacing between pads.
  • The 1025-18K is rated for operation up to 125°C, but derating is required for temperatures above 85°C. Consult the manufacturer's temperature derating chart for specific guidance.
  • The 1025-18K is designed for high-frequency applications up to 1 GHz. However, the inductor's self-resonant frequency (SRF) is around 300 MHz, and impedance may vary significantly above this frequency.
  • The 1025-18K has a maximum current rating of 18.5 A, but this rating is dependent on the operating temperature and frequency. Consult the manufacturer's current derating chart for specific guidance.
  • Yes, the 1025-18K is suitable for switching regulator applications due to its low core loss and high saturation current. However, ensure the inductor is properly sized and selected for the specific application requirements.
