Self-recovery fuse knowledge solution
The storage period of polymer PTC thermistor, also called self-recovery fuse, has no time limit. It can be stored for a long time under normal storage conditions of electrical components. If exposed to excessive humidity or high temperature, the performance of some specifications may change, such as the solderability of tin and lead.

China's thermistor industry main application market demand outlook-Huagu Electronics.
Thermistor is a kind of sensitive components, according to the temperature coefficient is divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC). The typical characteristic of thermistors is that they are sensitive to temperature and exhibit different resistance values at different temperatures. The positive temperature coefficient thermistor (PTC) has a larger resistance value when the temperature is higher, and the negative temperature coefficient thermistor (NTC) has a lower resistance value when the temperature is higher. They belong to the same semiconductor device.

Huaju Electronics New Energy Vehicle Temperature Sensor Leading in National Sales-Huaju Electronics
NTC (negative temperature coefficient) thermistor is a kind of thermal semiconductor resistor, its resistance value decreases with the increase of temperature. The temperature coefficient of resistance is in the range of-2%/k ~-6%/k, which is about 10 times of the temperature coefficient of metal resistance. The change in the resistance value of the NTC thermistor may be caused by a change in the external ambient temperature, or may be caused by self-heating due to a current flowing therethrough. His various uses are based on this characteristic. The NTC thermistor is composed of a mixed oxide polycrystalline ceramic. The conductive mechanism of this material is quite complex.

History and Industry Development of Varistors-Huagu Electronics
From 1929 to 1930, the United States and Germany almost simultaneously made high-voltage arresters with silicon carbide pressure-sensitive materials. At the end of the 1940 s, the Soviet Union made low-voltage silicon carbide varistors. In 1968, Japan developed a zinc oxide pressure sensitive material. This material has more excellent electrical properties than other materials, and is still widely used. Other metal oxide (Fe2O3, TiO, etc.) varistors have also been developed.

The parameters of the varistor and the detection method-Huagu Electronics.
Many people have already known about varistors: varistors are voltage-limiting protection devices. Using the nonlinear characteristics of the varistor, when the over-voltage appears between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, so as to realize the protection of the post-stage circuit. So, what are the parameters and detection methods of the varistor?
