DFK-20-0001 - SCHURTER

DFK-20-0001 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and spacing for the DFK-20-0001?
  Schurter recommends a minimum PCB spacing of 2.5mm between the fuse and other components, and a minimum of 1.5mm between the fuse and the PCB edge. A larger spacing is recommended for high-voltage applications.
• Can the DFK-20-0001 be used in high-temperature applications?
  The DFK-20-0001 is rated for operation up to 125°C, but its performance may degrade above 100°C. For high-temperature applications, Schurter recommends using a fuse with a higher temperature rating, such as the DFK-20-0002.
• How do I select the correct fuse value for my application?
  To select the correct fuse value, consider the maximum current rating of your circuit, the voltage rating, and the fault current rating. Schurter provides a fuse selection guide on their website to help with this process.
• Is the DFK-20-0001 compatible with lead-free soldering processes?
  Yes, the DFK-20-0001 is compatible with lead-free soldering processes, such as SAC305 or Sn96.5Ag3Cu0.5. However, Schurter recommends following their recommended soldering profile to ensure reliable connections.
• Can the DFK-20-0001 be used in outdoor or harsh environmental applications?
  The DFK-20-0001 is rated for indoor use only. For outdoor or harsh environmental applications, Schurter recommends using a fuse with a higher environmental rating, such as the DFK-20-0003.
