V201HG34

TVS - Varistors, MOVs

The V201HG34 is a type of variable resistor commonly used in many different applications. It is also known as a "varistor" or "MOV" (Metal-Oxide Varistor) and it has become incredibly popular as a protection component in many types of electronic devices. In this article, we will discuss the application field and working principle of this valuable component.

Application Field of V201HG34

The V201HG34 is a popular solution for a number of protection applications. It can prevent damage to electronic devices from voltage surges, power cycling, and other types of electrical events. In the telecommunications industry, these components are particularly useful for protecting electronic switching equipment from voltage transients. The component also makes for excellent protection against electromagnetic interference (EMI) and radio frequency interference (RFI). It has been used in the automotive industry for many years to guard against over-voltage or reverse polarity.

In addition to the abovementioned areas of application, this type of varistor is also used in industrial applications to protect against lightning and other forms of electrical power disturbances. It is even used in the fields of medical equipment, broadcasting, and consumer electronics.

Working Principle of V201HG34

The V201HG34 varistor is made of an ceramics insulator with two welding electrodes on both ends. Metal-oxide particles are also added to the device for better performance. It works by immediately responding to a sudden change in voltage - usually by diverting the power to a ground point. This helps to limit the amount of current that passes through the system and reduce the risk of damage to vulnerable components.

In order to work, the varistor has to be connected to a power circuit on one side and grounded on the other. When the voltage exceeds a certain threshold, the varistor will react to the sudden shift in voltage by activating a counteracting current. This will restrict the flow of the initial current and help to protect the components downstream from any form of damage.

Conclusion

The V201HG34 Metal-Oxide Varistor is an important component for protecting electronic devices and systems from voltage transients, power cycling, lightning, and other electrical power disturbances. It works by responding to sudden changes in voltage and diverting the energy to a ground point in order to reduce the risk of damage to vulnerable components. As such, it is widely used across many different industries and application areas.
