Examples include a loss of a neutral conductor or shorted lines on the high voltage system. A user may have no indication when the surge suppressor has failed. Wikimedia Commons has media related to Varistors. 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.
Potentiometer digital Variable capacitor Varicap. 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.
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. However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for example, k lightning without significant degradation.
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 Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch. 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.

Adhesive Tape Applications Bond electrical components to heat sinks. Please verify that the product number that you select is available in the proper size and color to meet your specification. The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel.
The term is only used for non-ohmic varying resistors. Both types are available over a wide k varistor datasheet of voltages.

Under normal utility voltage conditions, this is not a problem. Another type of transient suppressor is the gas-tube suppressor.
The physical properties listed are typical values and are not ratasheet be considered as specifications. K varistor datasheet low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size.
Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors. MOVs are specified according to the voltage range that eatasheet can tolerate without damage. It is provided in roll form with a release liner on both sides for ease of application. Specification compliance is dynamic and should only be used as a general guide.
Information is given in good faith, but without warranty. Grisdale in the early s was used to guard telephone lines from lightning.
Always confirm that the tape you are interested in currently complies with all specification requirements. They have peak current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0. K was designed to bond electrical components to heat sinks.
Our suggestions for use are based on tests we believe to be reliable. 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.
Saint-Gobain Performance Plastics Technical Data Sheets
At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised. 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.
Data provided by Budnick Converting, Inc. Electrical components Resistive components. In contrast to a diode however, it has the same characteristic for both directions of traversing current. 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.
Application of sustained over-voltage to a MOV can cause high dissipation, potentially resulting in the MOV device catching fire. Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor. K is a 5 mil, double coated, thermally conductive KaptonT film with acrylic adhesive on both sides.
If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now without any surge protection. The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating. 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.
However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use.
