ASMDC125F/33-2 Frequently Asked Questions (FAQs)

  • The recommended PCB footprint for the ASMDC125F/33-2 is a rectangular pad with dimensions of 3.5mm x 2.5mm, with a 1.5mm diameter hole in the center for the fuse's leads.
  • The ASMDC125F/33-2 is rated for operation up to 125°C, but it's recommended to derate the fuse's current rating by 1.5% for every 1°C above 85°C to ensure reliable operation.
  • To determine the correct fuse value, calculate the maximum current that your circuit can handle, and then select a fuse with a current rating that is at least 1.5 to 2 times the maximum current. Also, consider the fuse's voltage rating, which should be equal to or greater than the circuit voltage.
  • The ASMDC125F/33-2 has a voltage rating of 33V, making it suitable for low-voltage applications. For high-voltage applications, consider using a fuse with a higher voltage rating, such as the ASMDC125F/63-2, which has a voltage rating of 63V.
  • The typical response time of the ASMDC125F/33-2 is around 1-2 seconds for currents above the fuse's rated current. However, this time may vary depending on the application and the type of fault.
