Our suggestions for use are based on tests we believe to be reliable. Another type of transient suppressor is the gas-tube suppressor.

Specification compliance is dynamic and should only be used as a general guide. Adhesive Tape Applications Bond electrical components to heat sinks.
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. In contrast to a diode however, it has the same characteristic for both directions of traversing current. The main parameter affecting varistor life expectancy is its k varistor datasheet Joule rating.
Electrical datasehet Resistive components. 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.
Unfortunately, these devices may have higher breakdown voltages and longer response times than 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.

MOVs are specified according to the voltage range that they can tolerate without damage. Capacitor types Ceramic resonator Crystal oscillator Inductor Parametron Relay reed relay mercury switch. Data provided by Budnick Converting, Inc. 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.
K was designed to bond electrical components to heat sinks. They have peak current ratings k varistor datasheet about 20 to amperes, and peak energy k varistor datasheet from 0. K varistor datasheet low-capacitance varistors are, however, unable to withstand large surge currents simply due to their compact PCB-mount size. 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. Both types are available over a wide k varistor datasheet of voltages. A user may have no indication when the surge suppressor has failed. 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.
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. Examples include a loss of a neutral conductor or shorted lines on the high voltage system.
Always confirm that the tape you are interested in fatasheet complies with all specification requirements. K is a 5 mil, double coated, thermally conductive KaptonT film with acrylic adhesive on both sides. However, they can handle significantly higher fault currents and withstand multiple high-voltage hits for datasheet, k lightning without significant degradation. Potentiometer digital Variable capacitor Varicap.
Depending on the level of conducted current, dissipated heat may be 2k75 to cause datashewt, but may degrade the MOV device and reduce its life expectancy.

Please verify that the product number that you select is available in the proper size and color to meet your specification. The physical properties listed are typical values and are not to be considered as specifications.
The term is only used for non-ohmic varying resistors. 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. 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, datasueet now without any surge protection.

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. Under normal utility voltage conditions, this is not a problem.
However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. 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. Wikimedia Commons has media related to Varistors.
