Please verify that the product number that you select is available in the proper size and color to meet your specification. K was designed to bond electrical components to heat sinks. A user may have no indication when the surge suppressor has failed.

Adhesive Tape Applications Bond electrical components to heat sinks. K varistor datasheet low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size. Under normal utility voltage conditions, this is not a problem. Multi-layer varistor MLV devices provide electrostatic discharge protection to electronic circuits from low to medium energy transients in sensitive equipment dtaasheet at volts dc.
K, Thermally Conductive Kapton® Tape, Saint-Gobain, adhesive tape datasheet
However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for example, k lightning without significant degradation. MOVs are specified according to the voltage range that they can tolerate without damage. 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. 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.
Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors. Varistors are used as k varistor datasheet or compensation datasjeet in circuits either to provide optimal operating conditions or datashfet protect against excessive transient voltages. Grisdale in the early s was used to guard telephone lines from lightning. The term is only used for non-ohmic varying resistors. 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.
They have peak current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0.
Another type of transient suppressor is the gas-tube suppressor. Wikimedia Commons has media related to Varistors. 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. Electrical components Resistive components.
Always confirm that the tape you are interested in currently complies with all specification requirements. Examples include a loss of a neutral conductor or shorted lines on the high voltage system. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use.

The datwsheet properties listed are typical values and are not to be considered as specifications. The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating.
In contrast to a diode however, it has the same characteristic for both directions m275 traversing current. Data provided by Budnick Converting, Inc. Depending on the level of conducted current, dissipated heat may be insufficient to cause failure, but may degrade the MOV device and dagasheet its life expectancy.
Specification compliance is dynamic and should only be used as a general guide. At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised.

If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now without any surge protection. 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.
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. J275 suggestions for use are based on tests we believe to be reliable. The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel.
Potentiometer digital Variable capacitor Varicap.
Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor. Both types are available over a wide k varistor datasheet of voltages.
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.
It is provided in roll form with a release liner on both sides for ease of application.
