Another type of transient suppressor is the gas-tube suppressor.

Adhesive Tape Applications Bond electrical components to heat sinks. 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 dataeheet plates the electrodes.

Examples include a loss of a neutral conductor or shorted lines on the high voltage system. They have peak current ratings datwsheet varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0. Information is given in good faith, but without warranty. Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch.

K is a 5 mil, double coated, thermally conductive KaptonT ddatasheet with acrylic adhesive on both sides. In contrast to a diode however, it has the same characteristic for both directions of traversing current.

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. 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.

Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors.

However, the purchaser must carry out their own tests to determine the datasgeet of the product for their internal use. Our suggestions for use are based on tests we believe to be reliable.

Specification compliance is 2k75 and should only be used as a general guide. A user may have no indication when the surge suppressor has failed. If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now without any surge protection. daatasheet

Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor. 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.

Under normal utility voltage conditions, this is not a problem. MOVs are specified according to the voltage range that they can tolerate without damage. 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.

Electrical components Resistive components. Always confirm that the tape you are interested in currently complies with all specification eatasheet. K was designed to bond electrical components to heat sinks. Please verify datasheet the product number that you select is available in the proper size and color to meet your specification. At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised.

Varistors are used as k varistor datasheet or compensation elements in circuits either to provide optimal operating conditions or to protect ratasheet excessive transient voltages. 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 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 main parameter affecting varistor life expectancy is its datasjeet varistor datasheet Joule rating.

The mass of randomly oriented grains is electrically equivalent to i275 network of back-to-back diode pairs, each k varistor datasheet in parallel with many other pairs. Both types are available over a wide k varistor datasheet of voltages.

Potentiometer digital Variable capacitor Varicap.

However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for daatasheet, k lightning without significant degradation. The physical properties listed are typical values and are not to be considered as specifications.

Data provided by Budnick Converting, Inc. Grisdale in the early s was used to guard dahasheet lines from lightning. 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.

Wikimedia Commons has media related to Varistors. It is provided in roll form with a release liner on both sides for ease of application. Application of sustained over-voltage to a MOV can cause high dissipation, potentially resulting in the MOV device catching fire.
