WebAug 31, 2024 · Let’s first consider varistor failure caused by heating. At lower currents, the heating localizes in strings of tiny hot spots, which occur at the grain boundaries where the potential is dropped across Schottky-type barriers (see Figure 3). The heat transfer in this case is too fast to permit temperature differences that could cause failure. WebT hick film resistor failure is rarely caused by a failure of the resistive element but is generally due to external environmental factors such as mechanical and electrical stresses and handling issues. Failures can be either classed as a degradation of performance or complete failure (usually as an open rather than a short circuit).
