TVS (Transient Voltage Suppressor) - Varistors, MOVs (Metal Oxide Varistors) are generally accepted as components the protection of circuits against electrical transients. This protection is provided by absorbing r unwanted electrical energy in an electronic component. The VP4032K122R130 is one type of TVS - Varistors, MOVs used to protect electrical circuits.

The VP4032K122R130 is an axial leaded two-terminal varistor. A varistor is a non-linear voltage dependent resistor that can be connected to a circuit either in series or parallel. It is mainly composed of zinc oxide grains suspended in a ceramic binder. Its electrical characteristics are generally bidirectional, symmetric and non-linear, which makes it suitable in applications such as surge protection, line filtering, impedance balancing, and voltage limitation.

The VP4032K122R130 is designed for AC line-to-ground applications. It provides a low-distortion, low-voltage protection in the frequency range of 20 to 200 Hz. It is rated to withstand a peak voltage of 132 V and a repetitive peak voltage of 80 V. Its maximum operating temperature is stated as 85 degrees Celsius. The VP4032K122R130 has a non-linear capacitance characteristic, which means it is capable of absorbing electrical transients up to the rated peak voltage. Its clamping voltage is specified as 0.75 volts, with a response time of 1.7 μs.

The working principle of the VP4032K122R130 is relatively simple. When the circuit voltage reaches the rated peak voltage or higher, the zinc oxide grains in the varistor\'s body essentially "melt", thereby reducing the resistance of the varistor and allowing a large current to flow through it, thus protecting the circuit from the transient. The VP4032K122R130 is also capable of limiting transient voltage, thanks to its non-linear capacitance which absorbs the energy of the transient.

The VP4032K122R130 is widely used in AC line-to-ground applications and is suitable for use across a broad frequency range. It is commonly used in telecommunications, power, appliance, and automotive applications. Additionally, it is also used in industrial equipment. Its small size and low cost make it a cost-effective solution for these applications.

In conclusion, the VP4032K122R130 is an excellent choice for AC line-to-ground protection,  line filtering, impedance balancing, and voltage limitation. It is designed for maximum reliability and is relatively easy to install. Its low cost and compact size make it a versatile and cost-effective solution for many AC line-to-ground applications.
