    Varistor product introduction:
    Varistor is a kind of metal oxide semiconductor nonlinear ceramic resistance element with zinc oxide as the main component. According to its voltammetry characteristics, it can be divided into two types: symmetric (non-polar) and asymmetric (polar). Resistance is more sensitive to voltage,
    When the voltage reaches a certain value, the resistance quickly switches on. Because the varistor has good non-line characteristics. Large flow, fast action and no continuous flow, etc., are widely used as surge protectors, lightning surge protectors and electronics
    Voltage equipment lightning protection to prevent such overvoltages from interfering with the normal operation of electronic voltage equipment or damaging various circuit components.

    application of varistor:
    Products as surge protectors are widely used in various fields of electronic engineering:
    1. Communication,
    2. Electricity,
    3. Home appliances,
    Specific such as: telephone, switch, electricity meter, distribution cabinet, socket box, distribution box, power switch, power surge protection box, power voltage regulator, lightning arrester (SPD surge protection special) and so on.

    metal oxide varistor working principle:
    When at rest, varistors have a high impedance (several megohm) relative to the protected electronic components and do not change the circuit characteristics of the original design
    When a transient surge voltage occurs (exceeding the breakdown voltage of the varistor), the impedance of the varistor becomes low (only a few ohms) and causes a short circuit of the original line.
    In other words, the electronic product or component is also protected.

    Advantages of varistors:
    1. Wide voltage range
    2. Large flow capacity, large energy tolerance
    3. Large nonlinear coefficient
    4. Small leakage current
    5. Symmetrical volt-ampere characteristics
    6. Residual depression
    7. Fast action, small response time
    8. No continuous flow
    9. Good voltage ratio
    10. Strong surge absorption capacity
    11. High efficiency surge current processing capability
    12. Stable execution ability of suppressed voltage characteristics
    13. Excellent material
    14. Work reliably
    15. Long life
    16. Widely used
