So, does the diameter of the varistor relate to the flux? The larger the diameter of the varistor, the higher the flux. In general, the voltage sensitivity of the manufacturer of varistor dredging is based on the criteria. That is to say, the variable-rate index of the variable-voltage is not higher than 10% according to the impulse of 2 / 5 waveform according to the voltage sensitivity criterion. Pass. One of the current pass criteria for varistors is that 2 / 5 waveforms hit 2500A once and 1250A twice. Another current passage criterion is 2 / 5 waveform shocks 4500A at a time and 2500A twice.
If the circuit is different, the input voltage and current are different. If the current is too large, it will destroy important devices. Voltage sensitive resistor is a device with limited voltage protection in a special voltage region. It is very important to add high voltage sensitive voltage, but not to present such a high transient voltage in real use, so it can not play its due function. If the voltage is low, it will often be in a working situation, not only when the service life is affected, but some will be burned out.
The larger the diameter of the varistor, the higher the flux. Generally speaking, the manufacturer of varistor dredge the voltage sensitivity according to the criteria. That is to say, the variable-rate index of the variable-voltage is not higher than 10% according to the impulse of 2 / 5 waveform according to the voltage sensitivity criterion. Pass. Different circuits, different voltages and currents. If the current is too large, it will destroy important devices.
