Varistor JVR-14N 470K

Jvr 10nk datasheet pdf pinout metal oxide varistor. Datasheet search engine for electronic components and semiconductors.

It expresses the diode-like behavior in both directions of current flow. In the United States, a power strip protector should have an Underwriters Laboratories UL 3rd edition approval so that catastrophic MOV failure does not create a fire hazard. The current in a varistor is proportional to applied voltage raised to a power. A varistor provides no equipment protection from inrush current surges during equipment startupfrom overcurrent created by a short circuitor from voltage sags also known as a brownout ; it neither senses nor affects such events.

Cumulative degradation occurs as more surges happen. Shenzhen Jinmaoyuan Technology Co. This section needs expansion. A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Under normal utility voltage conditions, this is not a problem. Thinking ntcptcpolymer ptc thermistor, varistor mov. The term is only used for non-ohmic varying resistors. A user may have no indication when the surge suppressor has failed. Under the right conditions of over-voltage and line impedance, it may be possible to varstor the MOV to burst into flames, [17] the root cause of many fires vqristor and the main reason for NFPA’s concern resulting in UL in and subsequent revisions in and Dongguan Chengdong Electronic Technological Co.

Varistor JVRN K – Zinc oxide varistors – Micros

To protect telecommunication lines, transient suppression devices such as 3 mil carbon blocks IEEE Jfr The maximum power that can be applied within the specified ambient temperature. Traditional varistor schematic symbol, [5] used today for the diac. Western Electric 3B varistor made in for use as click suppressor in telephone sets.

Electrical components Resistive components. Low-cost versions may use only one varistor, from the hot live, active to the neutral conductor.

The sub-nanosecond MOV response claim is based on the material’s intrinsic response time, but will be slowed down by other factors such as the inductance of component leads and varietor mounting method [15]. Nanyang Keda Electric Co.

Jvr20nk data sheet, alldatasheet, free, databook. For higher frequencies, such as radio communication equipment, mvr gas discharge tube GDT may be utilized.

The result of this behaviour is a highly nonlinear current-voltage characteristic, in which the MOV has a high resistance at low voltages and a low resistance at high voltages. Unfortunately, these devices may have higher breakdown voltages and longer response times than varistors.

At low voltage the varistor has a high electrical resistance which decreases as the voltage is raised. Yueqing Hecheng Electrical Co. Shenzhen Yike Technology Co. Rosch Hardware Bible 6th ed. Patch panel,keystone jack,crimping tools,fiber optic,terminal block.

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. On long varistpr, the varistors maintained a relatively high resistance and did not alter the signals significantly. Wikimedia Commons has media related to Varistors.

When a large voltage is applied, the diode junction breaks down due to a combination of thermionic emission and electron tunnelingand a large current flows.
