Another type of transient suppressor is the gas-tube suppressor. Examples include a loss of a neutral conductor or shorted lines on the high voltage system. The term is only used for non-ohmic varying resistors.

K was designed to bond electrical components to heat sinks. Specification compliance is dynamic and should only be used as a general guide. If excessive current is conducted by a MOV, it may fail catastrophically, keeping the load connected, but now without any surge protection. Varlstor current resulting from a strike may melt, burn, or even vaporize the varistor.

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. Grisdale in the early s was used to guard telephone lines from lightning. MOVs are specified according to the voltage range that they can tolerate without damage.

They have eatasheet current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0. The physical properties listed are typical values and are not to be considered as specifications.

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. 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.

The probability of catastrophic failure can be reduced by increasing the rating, or using specially selected MOVs in parallel. K is a 5 mil, double coated, thermally conductive K257 film with acrylic adhesive on both sides. Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch.

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. 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.

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.

However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. A user may have no indication when the surge suppressor has failed. Potentiometer digital Variable capacitor Varicap.

However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for example, k lightning without significant degradation. It is provided in roll form with a release liner on both sides for ease of application.

The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating. This is a type daasheet spark gap xatasheet 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. Information is given in good faith, but without warranty. Please verify that the product number that you select is available in the proper size and color to meet your specification.

Data provided by Budnick Converting, Inc. 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.

Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors. Under normal utility voltage conditions, this is not a problem. Electrical components Resistive components.

Always confirm that the tape you are interested in currently complies with all specification requirements. 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.

At low voltage varisotr has a high electrical resistance which decreases as the voltage is raised. This type contains a ceramic mass of zinc oxide grains, in a matrix dayasheet other metal k varistor datasheet such as small amounts of bismuth, cobalt, manganese sandwiched between datzsheet metal plates the electrodes. In contrast to a diode however, it has the same characteristic for both directions of traversing current.

K varistor ,275 low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size.
