What material is a fuse? I believe everyone has an impression of fuses. In the old days, the materials used for fuses were not as diverse as they are now, and they were not fully popularized. A few years ago, most household circuit meters used safety tubes. After the safety tube broke, it was very troublesome to purchase a safety tube. Everyone directly used copper wire to replace it. Although the fuse effect could also be considered, it was very unsafe and could easily damage electronic products.

The specific power supply circuit of the fuse and the fuse clip is the same as that of the protected circuit. However, overvoltage protection is referenced by fuses and fuse clips supplying all signal input terminal voltages, and the supply voltage is changed to suite under protection circuit requirements. The voltage range may range from the absolute maximum rated SP720 to 4.5V power level.

A fuse is an electrical component installed in a circuit to ensure safe operation of the circuit. When the circuit malfunctions or is abnormal, it may burn the circuit or even cause a fire. Some fuses have a blown indicator device, which is used to indicate that when the fuse is activated (blown), it undergoes a certain appearance change and is easily detected by maintenance personnel. So what are the components of a fuse?

What's a fuse? This is a magical little object that will self-destruct when there is a state of surge current. So why create a device like this? The reason is simple: protect the rest of the circuit where the fuse is located,

Varistor is an all-too-familiar word for technical engineers. So for the small white project, it should be a time to deeply understand and explore the function and performance of the varistor. Xiaobian here will not be around the topic, here? Kester technology Xiaobian brings you: the basic performance of varistor in circuit function and protection. The following is the analysis of the data prepared by Xiaobian for you:

Varistor is a special resistance device whose resistance value changes significantly with the change of current or voltage. Therefore, varistors are often used in circuits for the suppression of fast electromagnetic interference, and for the protection of overvoltage and overcurrent in circuits. In some applications, the role of varistor series is also widely used. The role of varistors in series is to expand the operating voltage range of the circuit and enhance the stability of the circuit. Normally, varistors are connected in series in the circuit.
