Basic parameters of varistor 2

1. Residual voltage ratio: When the current passing through the varistor is a certain value, the voltage generated at both ends of it is called the residual voltage of this current value. The residual voltage ratio is the ratio of the residual voltage to the nominal voltage.

2. Current capacity (kA): The current capacity is also called the flow rate, which refers to the maximum pulse (peak value) allowed to pass through the varistor under specified conditions (specified time interval and number of times, applying standard impulse current) Current value.

3. Leakage current (mA): Leakage current, also known as waiting current, refers to the current flowing through the varistor under the specified temperature and maximum DC voltage.
