Варисторы дисковые оксидно-цинковые импортные. Варисторы представляют собой полупроводниковые резисторы с симметричной вольт-амперной характеристикой, похожей на ВАХ стабилитронов. Их отличительной особенностью является резко выраженная зависимость сопротивления от приложенного к ним напряжения. Варисторы используются для стабилизации и защиты электронного оборудования от перенапряжений, преобразования частоты и напряжения, а также регулирования в системах автоматики.
Система обозначений

1. Варистор оксидно-цинковый дисковый
2. Диаметр диска, мм
3. Классификационное напряжение, В, при токе 1 мА. Классификационное напряжение не является рабочим эксплуатационным напряжением варистора. Варистор выбирается исходя из допустимой поглощаемой энергии и максимально допустимого напряжения.
(Кодовое обозначение: первые две цифры – значение в вольтах, третья – множитель. Пример: 271 = 27 В х 101 = 270 В).
