37400500000 Datasheet/PDFFuses are extremely important electronic components used to protect circuits from high current in electric and electronic products. The 374050000 application field and the working principle can be divided into three parts: applications, working principle and types.
Applications
Fuses are widely used in many fields, such as automotive, aerospace, military, and public transportation. Automotive applications include engines, airbags, wipers, and lights. In addition, they are also used in electric and electronic products, such as home appliances, computers, medical equipment, information networks, and other equipment. Automotives also use fuses to protect their electrical systems from damage caused by short circuits.
Working Principle
The working principle of a fuse is fairly simple but effective. When a predetermined amount of current passes through the fuse, an internal spring or wire melts, opening a gap in the circuit, thereby interrupting the current. This gap prevents current from flowing through, improving safety and reducing the risk of damage to an electric or electronic system. The gap size of a fuse depends on the size of the spring or wire. The larger the gap, the smaller the current that can pass through.
Types
There are several types of fuses. The most commonly used type is the cartridge fuse, which is available in different shapes and sizes. It is the most commonly used fuse in automobiles. In addition, there are also blade fuses, slab fuses, knife fuses, and plug fuses. Blade fuses are typically used for larger currents, while plug fuses are used for smaller currents. Knife fuses are different in that they use a metal blade instead of a spring or wire to open the gap.
Fuses are extremely important components in electric and electronic products. The 374050000 application field and the working principle are important to understand in order to determine which type of fuse is most suitable for a particular application. With proper selection and use, the risk of damage to an electronic system due to a short circuit is greatly reduced.
