Resistors are classified according to their volt ampere characteristics: for most conductors, their resistance remains almost constant at a certain temperature and remains at a certain value. This type of resistance is called linear resistance. The resistance of some materials varies significantly with the current, and their volt ampere characteristics are a curve. This type of resistance is called nonlinear resistance. The ratio of voltage to current of a nonlinear resistor under a given voltage is the static resistance at that operating point, and the slope on the V-A characteristic curve is the dynamic resistance.

What protection is the low-voltage fuse mainly used for, the fuse is a common component of the circuit, and the fuse has the same function. The application field of fuses is related to the type, and fuses can be divided into low voltage, high voltage, power, self-recovery, fast, photovoltaic and so on. Today, Xiaobian mainly introduces the application field of low-voltage fuses, please see the following.

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,
