Fuses

0448.080MR Application Field and Working Principle

Fuses are electronical components used to limit the amount of current that passes through them, protecting a system from an overload or short circuit. The 0448.080MR is an especially small fuse, providing reliable and efficient electrical current protection while taking up minimal real estate.The 0448.080MR\'s soft insertion makes it one of the most sensible selections for surface mounted applications. Its size and weight, combined with its durability, make it a great fit for more compact environments, like consumer electronics. Additionally, its glass body gives it an extended life in extreme operating temperatures, allowing it to be used in military and aerospace systems where other fuses would not be suitable.The 0448.080MR maintains a constant resistance across its entire range of operation, so as long as the load and voltage level is the same, the current will remain constant. It is designed to protect the circuit by blowing the fuse in the event it is overloaded, and can be quickly replaced without requiring the circuit to be dismantled.When the current passing through the 0448.080MR exceeds its rated value, a small arc is generated that jumps across the gap between the contacts. This causes the fuse link to melt, and disconnects the circuit. The 0448.080MR has a specific breaking current – the current at which the fuse link melts and separates the contacts – that is determined by the size and type of metal used in its construction.The 0448.080MR is able to protect circuits in a range of operating voltages, depending on the manufacturer. Typically, it is available in 60V, 32V, 25V, 12V, and 6V. Its rated current varies from 0.2A to 15A. Additionally, the 0448.080MR is RoHS compliant and UL listed.The 0448.080MR is a reliable and efficient solution for circuit protection on portable devices, industrial equipment, advanced systems on chips, and motherboards. It is very compact and durable, making it perfect for space-constrained systems, as well as military and aerospace applications. It is designed to quickly and accurately detect faulty or unacceptable current levels, and is approved by leading industry safety standards.
