RGEF300K-2 Frequently Asked Questions (FAQs)

  • The recommended PCB footprint for the RGEF300K-2 is a rectangular pad with dimensions of 3.5mm x 1.5mm, with a 1.5mm diameter hole in the center for the fuse's leads.
  • Yes, the RGEF300K-2 is rated for operation up to 125°C, making it suitable for high-temperature applications. However, the fuse's melting integral (I²t) may be affected at elevated temperatures.
  • To determine the correct fuse rating, you need to calculate the maximum fault current and fault duration in your application. You can use the fuse's I²t curve to select the appropriate fuse rating.
  • Yes, the RGEF300K-2 is compatible with lead-free soldering processes, with a peak reflow temperature of 260°C.
  • The RGEF300K-2 should be stored in a dry, cool place, away from direct sunlight and moisture. Handling should be done with anti-static wrist straps and mats to prevent electrostatic discharge damage.
