Varistor Function Overview
A varistor is a voltage-dependent resistor that changes resistance based on applied voltage. When voltage remains below the threshold (UN), current flow is minimal. When voltage exceeds UN, current surges dramatically, effectively clamping overvoltage conditions. This zinc oxide varistor provides reliable protection by limiting abnormal voltage spikes to safe levels, preventing damage to electronic circuits and components.
