30R110 Frequently Asked Questions (FAQs)

  • The recommended PCB footprint for the 30R110 is a rectangular pad with dimensions of 0.25 inches (6.4 mm) x 0.15 inches (3.8 mm) with a 0.05 inches (1.3 mm) radius corner. The pad should be centered on the component and have a minimum of 0.01 inches (0.25 mm) clearance from the edge of the board.
  • Yes, the 30R110 is rated for operation up to 150°C, making it suitable for high-temperature applications. However, it's essential to ensure that the device is properly derated for temperature to avoid thermal runaway and ensure reliable operation.
  • To select the correct fuse rating, you need to consider the maximum current and voltage in your circuit. The fuse rating should be higher than the maximum current and voltage to ensure that it doesn't blow unnecessarily. You should also consider the fault current and the time it takes for the fuse to clear the fault.
  • Yes, the 30R110 is compatible with lead-free soldering processes. Littelfuse Inc. has qualified the device for use with lead-free soldering processes, and it meets the requirements of the RoHS directive.
  • The typical response time of the 30R110 is around 1-2 seconds for a fault current of 100 A. However, this time can vary depending on the specific application and the fault current. It's essential to consult the datasheet and application notes for more information.
