0471002 MAT1L is a fast-acting fuse often used in applications operating at less than 30 volts of direct-current or less than 60 volts of alternating-current. It can be seen as a low-current-rated version of the basic MAT circuit protection element.

This fuse has earned an enviable reputation as a dependable, reliable, low-cost solution for a wide range of circuit protection needs. Primary uses are in consumer electronics, communications applications, and PC motherboards. It is approved to UL 248 Standard 10 and CSA Standard C22.2 No. 248.

Fuses typically have two important parameters – Current Rating and Interrupt Rating. The current rating is the maximum steady-state current the fuse can handle before it melts and disconnects the circuit. The interrupt rating is the amount of transient current the fuse can safely handle without damaging the fuse.

The 0471002 MAT1L has a nominal current rating of 1 amp and an interrupt rating of 500 amps. It can be used at voltages up to 60 volts AC/DC. It has a body length of 1.25 inches with a diameter of 0.375 inches and a typical body material of plated nickel. The wire gauge range is from 16 AWG through 30 AWG.

Generally, protector fuses like the 0471002 MAT1L are bimetal thermal fuses, which work by sensing temperature increases and responding by opening and breaking the circuit connection. The thermal fuse has two thin strips of conjoined metal; a metal with a low coefficient of thermal expansion, usually nickel, and a metal with a high coefficient of thermal expansion, usually tin. Under normal operating temperature, the strips are held together and form a conductive path. When a high temperature is applied to the strips, the strip with the higher coefficient of thermal expansion expands faster than the other and bends, breaking the connection.

The 0471002 MAT1L is also available in a lead-free version, which is even more reliable and compliant with Lead-Free RoHS standards. The 0471002 MAT1L is available in both through-hole and surface-mount versions, which makes it a very versatile fuse choice.

In summary, the 0471002 MAT1L fuse offers reliable, low-cost circuit protection for a wide variety of applications. Its small size, high current rating, and UL and CSA approval make it an attractive choice for many low-voltage circuits. It is also available in lead-free versions, making it even more eco-friendly.
