Fuses are a type of electrical device used to protect against short circuits or overvoltage in an electrical system. They are typically made of two metal strips that form a bridge when current passes through them, thereby opening and disconnecting the circuit. The 2JQ 2-R application field and working principle is no exception.

The 2JQ 2-R is used in the automotive industry to protect the Electrical Control System (ECS) from damage caused by short circuits. The 2JQ 2-R fuse is composed of a copper element, microchip, plastic casing, and brass end cap. The copper element behaves as a conductor, and when exposed to excessive current, it melts and opens the circuit. The microchip provides intelligence to detect and cut-off current. Finally, the plastic casing and brass end cap provide additional insulation and mechanical protection to the internal components.

The working principle of the 2JQ 2-R is relatively straightforward. When an excessive amount of current exceeds the rated current of the fuse, it activates the copper element, which melts and opens the circuit, thus cutting off the electrical power supply. The microchip can detect and recognize a sudden increase in current, and provide instantaneous protection before the current reaches the rated current of the fuse. In addition, the fuse also has a low self-induction current, meaning that the current is discharged only when it reaches the prescribed value.

The 2JQ 2-R fuse has a wide range of applications, and is ideal for protecting sensitive Electrical Control System (ECS) components from over-current events. It is widely used in automotive vehicles such as cars, trucks, buses, and motorcycles. Furthermore, it can be used in a variety of other electrical systems, such as communications, power distribution, medical, and industrial.

In conclusion, the 2JQ 2-R application field and working principle operates in the same manner as other fuses by using a copper element that melts when exposed to excessive current. A microchip is also included to detect and cut-off the current and provide instantaneous over-current protection. This fuse is used extensively in the automotive industry, as well as in a variety of other electrical systems.
