The term is only used for non-ohmic datashert resistors. A user may have no indication when the surge suppressor has failed. Our suggestions for use are based on tests we believe to be reliable. At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised. Information is given in good faith, but without warranty. When a large datasheey is applied, the diode junction k varistor datasheet down due to a combination of thermionic emission and electron tunnelingand a large current flows.
If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now without any surge protection. It is essential, as with all pressure-sensitive tapes, that the surface dataaheet which the tape is applied be clean, dry and free of grease and oil.

Application of sustained over-voltage to a MOV can cause high dissipation, potentially resulting in the MOV device catching fire. Both types are available over a wide k varistor datasheet of voltages. Potentiometer digital Variable capacitor Varicap. Datasheeg, these devices may have higher breakdown voltages and longer response times than varistors. 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.
Electrical components Resistive components. Grisdale in the early s was datashret to guard telephone lines from lightning. 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. 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.
Another type of transient suppressor is the gas-tube suppressor. The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel.
Please verify that the product number that you select is available in ddatasheet proper size and color to meet your specification. Always confirm that the tape you are interested in currently complies with all specification requirements. In contrast to a diode however, it has the same characteristic for both directions of traversing current. Data provided by Budnick Converting, Inc. Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor.
However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating.
Adhesive Tape Applications Bond electrical components to heat sinks. The physical properties listed are typical values and are not to be considered as specifications. Wikimedia Commons has media related to Varistors. Under normal utility voltage conditions, this is not a problem.
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. Examples datadheet a loss of a neutral conductor or shorted lines on the high voltage system.

MOVs are specified according to the voltage range that they can tolerate without damage. However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for example, k lightning without significant degradation.
Specification compliance is dynamic and should only be used as a general guide. 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.
Capacitor types Datashewt resonator Crystal datashedt Inductor Parametron Relay reed relay mercury switch. They have peak current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor k27 from 0. K is a 5 mil, double coated, thermally conductive KaptonT film with acrylic adhesive on both sides.
It is provided in roll form with a release liner on both sides for ease of application. K was designed to bond electrical components to heat sinks. Depending on the level of conducted current, dissipated heat may be insufficient to cause failure, but may degrade the MOV device and reduce its life expectancy.
K varistor datasheet low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size. 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.
