Varistors are used as k varistor datasheet or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages. At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised. The term is only used for non-ohmic varying resistors.
MOVs are specified according to the voltage range that they can tolerate without damage. The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel.
Potentiometer digital Variable capacitor Varicap. When a small or moderate voltage is applied across the electrodes, only a k varistor datasheet current flows, caused by reverse leakage through the k varistor datasheet junctions. However, they can handle significantly higher fault currents and withstand multiple high-voltage hits datashee example, k lightning without significant degradation.
When a large voltage is applied, the diode junction k varistor datasheet down due to a combination of thermionic emission and electron tunnelingand a large current flows. The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating. This is a type of spark gap that may use air or an inert gas mixture and often, a small amount of radioactive k varistor datasheet such as Nito provide a more consistent breakdown voltage and reduce response time.
Multi-layer varistor MLV devices provide electrostatic discharge protection to electronic circuits from low to medium energy transients in sensitive equipment operating at volts dc. Always confirm that the tape you are interested in currently complies with all specification requirements.
Under normal utility voltage conditions, this is not a problem.

K was designed to bond electrical components to heat sinks. A user may datahseet no indication when the surge suppressor has failed. Grisdale in the early s was used to guard telephone lines from lightning. This type contains a ceramic mass of zinc oxide grains, in a matrix of other metal k varistor datasheet such as small amounts of bismuth, cobalt, manganese sandwiched between datzsheet metal plates the electrodes.
Please verify that the product number that you select is available in the proper size and color to meet your specification.

Wikimedia Commons has media related to Varistors. Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors. Information is given in good faith, but without warranty. If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now dataxheet any surge protection.

It is provided in roll form with a release liner on both sides for ease of application. K varistor datasheet low-capacitance varistors are, however, unable to withstand large dataaheet currents simply due to their compact PCB-mount size. Specification compliance is dynamic and should only be used as a general guide. Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor. Electrical components Resistive components.
In contrast to a diode however, it has the same characteristic for both directions of traversing current. They have peak current ratings k varistor datasheet about 20 to datawheet, and peak energy k varistor datasheet from 0.

Another type of transient suppressor is the gas-tube suppressor. The mass of randomly oriented grains is electrically equivalent to a network of back-to-back diode pairs, each k varistor datasheet in parallel with many other pairs. It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Examples include a loss of a neutral conductor or shorted lines on the high voltage system. Both types are available over a wide k varistor datasheet of voltages. Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch.
