However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for example, from lightning without significant degradation.
Calculate the varistorr energy rating needed based on energy in transient voltage.
Metal Oxide Varistor
This page was last edited on 31 Decemberat Its non linear exponent characteristic, broad range and mass production makes this product suitable for.
Jvr05nk metal oxide varistor components datasheet pdf data sheet free from datasheet data sheet search for integrated circuits ic, semiconductors and caristor electronic components such as resistors, capacitors, transistors and diodes. Varistors with internal thermal protection are also available. Circuit of the traditional construction of varistors used as click suppressors in telephony. This thermal runaway is due to a lack of conformity in individual grain-boundary junctions, which leads to the failure of dominant current paths under thermal stress when the energy in a transient pulse normally measured in joules is too high i.
Potentiometer digital Variable capacitor Varicap. Shenzhen Yuzhouxin Electric Co. Electrical components Resistive components. Shenzhen Top Source Technology Co. Varistors are used as control or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages. The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel.
MOVs tend to be more suitable for higher voltages, because they can conduct the higher associated energies at less variwtor.
Archived from the original on MOVs are specified according to the voltage range that they can tolerate without damage. Shenzhen Jingdacheng Kvr Co. Although diodes do not have as much capacity to conduct large surges as MOVs, diodes are not degraded by smaller surges and can be implemented with a lower “clamping voltage”.

There are several issues to be noted regarding behavior of transient voltage surge suppressors TVSS incorporating MOVs under over-voltage conditions. Products includes ntc, varistor also known as mov, metal oxide varistor, vdr, chip varistor socalled mlv, ptc, pptc socalled resettable fuse, temperature sensors and gdt. The copper-oxide varistor exhibited a varying resistance in dependence on the polarity and magnitude of applied voltage. Metal oxide varistor features and applications jvr zinc oxide varistors zinc oxide varistor is a voltage dependent resistor with symmetrical voltagecurrent characteristics that is designed to protect all kinds of electronic devices or elements from switching and induced lightening surges.
Another type of transient suppressor is the gas-tube suppressor. Download or read online rfe international jvr10sl metal oxide varistor 10mm disc pdf datasheet. Hefei Wolian Industrial Co.

This arrangement provides low resistance varitor current flowing from the semiconducting oxide to the copper varietor, but a high resistance to current in the opposite direction, with the instantaneous resistance varying continuously with the voltage applied.
The maximum power that can be applied within the specified ambient temperature. A catastrophic failure occurs from not successfully limiting a very large surge from an event like a lightning strike, where the energy involved is many orders of magnitude greater than the varistor can handle. The most common modern type of varistor is the metal-oxide varistor MOV.
