WebSMD/SMT Varistors are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for SMD/SMT Varistors. WebVaristor je nelineární polovodičová součástka, jejíž odpor závisí na napětí. Je zhotovena slisováním a spékáním zrníček karbidu křemíku ( SiC) při teplotě kolem 1200 °C, nebo spékáním oxidů některých kovů - například zinku. První uvedené se označují jako karbidové varistory, druhé jako MOV (Metal Oxid ...
ZNR Series Varistors – Mouser
WebA multilayer SrTiO 3 varistor, comprising both the functions of a capacitor and a varistor, can be obtained. It works as an ordinary capacitor, which absorbs low-voltage noises and high-frequency noises, while it functions as a varistor when high-voltage pulses and static electricity are generated by surrounding electronic equipment. Webthe varistor voltage measured at 1 mA does not change by more than 10 % maximum. A surge in excess of the specified withstanding surge current may cause short circuits or package rupture with expulsion of material; it is therefore recommended that a fuse be put in the circuit using the varistor, or the varistor be used in a protective box netstock login yearsley
