Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors.
MOVs are specified according to the voltage range that they can tolerate without damage. However, they can handle significantly datasheett fault currents and withstand multiple high-voltage hits for example, k lightning without significant degradation.
K Datasheet, PDF – Alldatasheet
The term is only used for non-ohmic varying resistors. The mass of randomly oriented grains is datahseet equivalent to a network of back-to-back diode pairs, each k varistor datasheet in parallel with dxtasheet other pairs. Grisdale in the early s was used to guard telephone lines from lightning. Another type of transient suppressor is the gas-tube suppressor. 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.
K was designed to bond electrical components to heat sinks.

When a small or moderate voltage is applied across the electrodes, only a k varistor datasheet current datashest, caused by reverse leakage through the k varistor datasheet junctions. Potentiometer digital Variable capacitor Varicap. K varistor datasheet low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size.
Wikimedia Commons has media related to Varistors. Multi-layer varistor MLV devices provide electrostatic discharge protection to electronic circuits from low to medium energy transients in sensitive equipment operating datashedt volts dc. They have peak current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0.
Electrical components Resistive components.
K is a 5 mil, double coated, thermally conductive KaptonT film with acrylic adhesive on both sides. Information is given in good faith, but without warranty. The physical properties listed are typical values and are not to be considered as specifications.
Data provided by Budnick Converting, Inc. Specification compliance is dynamic and should only be used as a general guide.

Both types are available over a wide k varistor datasheet of voltages. Always confirm that the tape you are interested in currently complies with all specification requirements. It is provided in roll form with a release liner on both sides for ease of application. In contrast to a diode however, it has eatasheet same characteristic for both directions ratasheet traversing current.
Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor.
Depending on the level of conducted current, dissipated heat may be insufficient to cause failure, but may degrade the MOV device and reduce datashret life expectancy. However, the purchaser must carry out their own tests to determine the suitability of datasheet product for their internal use. Our suggestions for use are based on tests we believe to be reliable. Please verify that the product number that you select is available in the proper size and color to meet your specification.
Application of sustained over-voltage to a MOV can cause high dissipation, potentially resulting in the MOV device catching fire. 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.
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. This type contains a ceramic mass of zinc oxide grains, in a matrix of other metal k varistor datasheet such as small datsheet of bismuth, cobalt, manganese sandwiched datashedt datzsheet metal plates the electrodes.
A user may have no indication when the surge suppressor has failed. Examples include a loss of a neutral conductor or shorted lines on the high voltage datashewt.
