          How does the varistor use? Should pay attention to the use of pressure sensitive.

          How does the varistor use? How many points are there to pay attention to pressure sensitive use? First, we first introduce the pressure sensitive resistance: the varistor is a noun in the mainland of China and a variety of the semiconductor resistor. The "Zinc Oxide" (ZnO) varistor is now widely used, and its main material is composed of two valence elements (Zn) and six valence element oxygen (O). Therefore, from the point of view of material, the Zinc Oxide varistor is a kind of "II - VI" oxide semiconductor. In Taiwan, China, the varistor is called a "wave absorber", sometimes called an electric shock (surge) suppressor.
          A varistor should not be heard by most people. It means that the resistance value varies with voltage in a certain range of current and voltage, or that the resistance value is sensitive to voltage. What are the considerations in the use process, the following Xiaobian electronic tage to learn about the pace of.

Therefore, from the point of view of material, the Zinc Oxide varistor is a kind of "II - VI" oxide semiconductor. In Taiwan, China, the varistor is called a "sudden wave absorber", sometimes known as an "surge" suppressor (absorber).

          The varistor, short of VSR, is a voltage sensitive nonlinear over voltage protection semiconductor device. It is represented by a word symbol "RV" or "R" in the circuit.
          What should be paid attention to when using a varistor when the varistor is understood? The following is the Shenzhen tage varistor electronic technology provides small matters needing attention:
          1, in the application of surge pulse repetition, the surge peak current and surge energy of varistors do not exceed the prescribed value of "pulse life characteristic".
          2, the working voltage of varistors (continuously applied to voltage at two ends of varistors) should not exceed the "maximum continuous working voltage" listed in the varistors technical parameter list.
          3. The temperature of the working environment of the varistor should be within the scope stipulated in the technical conditions.
          4. The varistor should not be installed near the heat or flammable components. It is best to have a interval of more than 3 millimeters to avoid damage to the components.
          5. The peak current of surge through a varistor should not exceed the "maximum peak current" listed in the voltage sensitive resistor technical parameter table.
          6, when the surge pulse is applied repeatedly to the two ends of varistors in a short time, the designer should calculate the average power at this time and make it lower than the maximum static power listed in the varistor technology parameter list.
          The above is the introduction of pressure sensitive resistance and the use of attention, hoping to help the engineers.
