The VP4032K122R050 is a series of varistor or voltage-dependent resistor. These devices are small, discrete components designed to absorb transient electrical overvoltages and protect a device or circuit from voltage surges. They’re commonly used in telecommunications, computer, automotive, and consumer electronics. This article will explain the VP4032K122R050\'s application field and working principle.

Application Field

The VP4032K122R050 is a popular series of varistor produced by Vishay Corporation. It is a nonlinear, bipolar, MOV-type (Metal Oxide Varistor - a type of varistor) that protects electronic circuits from overvoltage transients. The device has an ultra-low capacitance, and offers excellent clamping performance with a wide range of voltage protection.

The VP4032K122R050 is commonly used in consumer electronics, automotive, and telecommunications applications. It is suitable for a wide range of operating temperatures, and meets international standards, such as UL, CSA, and EN. This makes it a reliable, cost-effective choice for a variety of applications.

It can be used to protect circuits from voltage transients caused by lightning, electrostatic discharges, and power line disturbances. It is also used to protect circuits from noise generated by microprocessors and other digital chips.

Working Principle

The VP4032K122R050 is a nonlinear, bidirectional, voltage-dependent resistor (VDR) with a nominal capacitance of 2.12 pF and peak rated voltage of 32 V. The device is constructed of two metal oxide layers, which form a continuous series connection between two contacts.

When current is passed through the device, the varistor acts as a resistor, reducing current flow. As the voltage across the device increases, the resistance decreases. When the voltage reaches the peak rated voltage (32 V), the current flow is limited and the device turns into an open circuit.

This phenomenon is known as the clamping effect. The clamping effect occurs when the voltage reaches the peak rated voltage and the MOVs limit the current, preventing it from overloading the circuit. This is why MOVs are so effective at protecting circuits from overvoltages.

The VP4032K122R050 has an energy rating of 500J, making it suitable for protecting circuits from power surges and lightning strikes. It has an operating temperature range of -40 to 85°C and a response time of less than 10 ns.

Conclusion

In conclusion, the VP4032K122R050 is a series of varistor produced by Vishay Corporation. It is a nonlinear, biporlar MOV-type designed to protect electronic circuits from overvoltage transients. It has a wide range of applications, including consumer electronics, automotive, and telecommunications. In addition, it has an ultra low capacitance and a wide range of voltage protection. It also has a good clamping effect and a response time of less than 10 ns.
