TVS - Varistors, MOVs is one of the widely used components, and ROV05H820K-2 is a popular varistor in this category. This article covers the application field and working principles of ROV05H820K-2.

Introduction

The ROV05H820K-2 varistor is a recirculation type varistor, typically used in TVS - Varistors, MOVs applications. It is a nonlinear resistor that can be used to help protect sensitive electronic circuits from voltage and surge spikes. It can also protect against any transient voltage spikes that may occur in the power or electrical supply.

Application Field

The ROV05H820K-2 varistor is a versatile component and can be used in a variety of TVS - Varistors, MOVs applications. These include:

• Surge protection: The ROV05H820K-2 varistor can provide effective protection against overvoltage surges that can occur due to accidental contact with high voltage equipment or power lines. It can also help protect sensitive electronic components from high voltage spikes caused by lightning, power outages, or other types of electrical power disturbances.
• Noise suppression: The varistor can help reduce or eliminate low-frequency electrical noise interference from radios, cell phones, ELV systems, and other sources. This can be particularly important in applications where low levels of noise can cause systems to malfunction.

The ROV05H820K-2 varistor is also commonly used in medical equipment, industrial automation, and automotive electronics.

Working Principle

The working principle of ROV05H820K-2 varistor involves the use of a special nonlinear resistor. It works by responding to a voltage spike by changing its electrical resistance. This helps to “clamp” or limit the magnitude of the surge and dissipate it as heat. This helps to protect sensitive equipment from the potentially damaging effects of the surge.

The varistor is also designed to react quickly to a surge and limit its magnitude within a few microseconds. This helps to ensure that the sensitive components connected to it are not damaged by the surge.

Conclusion

The ROV05H820K-2 varistor is a commonly used component in TVS - Varistors, MOVs applications. It has a wide range of applications, from surge protection to noise suppression. Its working principle involves the use of a special nonlinear resistor, which quickly responds to voltage spikes and helps to protect sensitive electronic components from damage.
