*FAQ:
Q: What is the working principle of a varistor?
A: When the voltage applied to the varistor is lower than its threshold, the current flowing through it is extremely small, which is equivalent to a resistor with infinite resistance. In other words, when the voltage applied to it is lower than its threshold, it is equivalent to an off-state switch.
When the voltage applied to the varistor exceeds its threshold, the current flowing through it increases sharply, which is equivalent to a resistor with infinite resistance. In other words, when the voltage applied to it is higher than its threshold, it is equivalent to a closed switch. The varistor can clamp the voltage to a relatively fixed voltage value, so as to protect the subsequent circuit.
Q: What is the role of a varistor?
A: The biggest characteristic of a varistor is that when the voltage applied to it is lower than its threshold, the current flowing through it is extremely small, which is equivalent to a closed valve. When the voltage exceeds the threshold, the current flowing through it surges. , Which is equivalent to opening the valve. Using this function, the abnormal overvoltage that often appears in the circuit can be suppressed, and the circuit can be protected from overvoltage damage.
