Another type of transient suppressor is the gas-tube suppressor.
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.
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.
K VARISTOR DATASHEET DOWNLOAD
They have peak current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0. Wikimedia Commons has media related to Varistors. Information is given in good faith, but without warranty. Data provided by Budnick Converting, Inc. 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 fatasheet 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. Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor. 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.
The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel. Electrical components Resistive components.
Specification compliance is dynamic and should only be used as a general guide. K was designed to bond electrical components to heat sinks. 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.
The term is only used for non-ohmic varying resistors. Please verify that the product number that you select is available in the proper size and color to meet your specification.
MOVs are specified according to the voltage range that they can tolerate without damage. Multi-layer datashedt MLV devices provide electrostatic discharge protection to electronic circuits from low to medium energy transients in sensitive equipment operating datashet volts dc.
However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for example, k lightning without significant degradation.
The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating. K is a 5 mil, double coated, thermally conductive KaptonT film with acrylic adhesive on both sides.
Adhesive Tape Applications Bond electrical components to heat sinks. Both types are available over a wide k varistor datasheet of voltages. Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors.
Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch.
It is provided in roll form with a release liner on both sides for ease of application. A user may have no indication when the surge suppressor has failed.
The physical properties listed are typical values and are not to be considered as specifications. If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now without any surge protection.
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. At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised. Under normal utility voltage conditions, this is not a problem.
K 275 – Ceramic yarn cord
Application of sustained over-voltage to a MOV can cause high dissipation, potentially resulting in the MOV device catching fire. Our suggestions for use are based on tests we believe to be reliable. K varistor datasheet low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size.
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. 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.
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. Potentiometer digital Variable capacitor Varicap. In contrast to a diode however, it has the same characteristic for both directions of traversing current.
