Varistors, also known as Voltage Dependent Resistors (VDR), are special resistors whose resistance value changes with the applied voltage. These voltage-dependent resistors are used to protect electronic circuits from overvoltages and voltage spikes by dramatically increasing the current flow when a certain voltage is reached, thereby dissipating the excess energy.Varistors are typically used to protect electronic circuits and are found in many electronic devices and systems - from household appliances to industrial equipment to communications systems.
Voltage-dependent resistors are essential components in electrical engineering to ensure the longevity and safety of electronic components. Manufacturing varistors requires precise control of material composition and manufacturing process to ensure consistent performance
