    Product description

     

       Zinc oxide varistor, also known as surge absorber, is a pressure sensitive property resistor with symmetrical characteristics of voltage and current. Its main design is to protect all electronic products or components from the surge caused by switching or lightning strikes, and its nonlinear index characteristics and wide range of applications and mass production, has gradually The ground is applied to electronic engineering in various fields.

    Product advantages

     

       1. Low standby power and no subsequent current


       2. High-performance surge current handling capability

     

       3. Low standby power and no subsequent current


       4. Suppress the stable performance of voltage characteristics

     

     

     

    Use attention

     

      1. When a varistor is used between the power line and the ground, the voltage between the line and the ground may rise due to poor grounding. Therefore, a varistor with a higher nominal voltage than the line-to-line use is usually used.


      2. In applications where surge currents are repeatedly generated, the peak surge current and surge energy through the varistor should not exceed the pulse life characteristics.


      3. The varistor should be protected from high temperature and high humidity such as wind, rain and water vapor. It should also avoid working under dust, salt and harmful gases. Protection box should be used if necessary.


      4. Direct exposure to the sun or the ambient temperature next to the heater may exceed the operating temperature that the varistor can withstand.

     

     

     

    working principle

     

        When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, which is equivalent to a resistor with an infinite value. That is, when the voltage applied to it is below its threshold, it is equivalent to an open state switch [1]. When the voltage applied to the varistor exceeds its threshold, the current flowing through it surges, which is equivalent to an infinitely small resistance. That is, when the voltage applied to it is above its threshold, it is equivalent to a closed state switch.
