Abstract
It has been nearly a quarter of a century since Matsuoka (1) reported the non-ohmic properties of ZnO ceramics. During that period ZnO-based ceramics with their highly nonlinear current-voltage characteristics have accrued more than half of the varistor market in numbers and nearly 80% of the market in value as reported by Okinaka and Hata (2). These electronic devices, often referred to as MOV’s, or metal oxide varistors, find applications as surge absorbers, surge arrestors and in micromotors. Although these ZnO-based devices probably have their single largest volume usage in high-voltage power distribution systems, it is becoming increasingly common to protect household applicances and personal computers with varistor devices. It is likely that most readers of this article utilize such a device to protect their personal computers.
