TVS – Varistors, MOVs are used as surge protection components in various fields. It is very important to understand the working principle of TVS – Varistors, MOVs. In this article, the application field and working principle of ROV05H471K-2 will be discussed.

1. Application Field of ROV05H471K-2
The ROV05H471K-2 can be used as surge protection components for sensitive electronic projects, such as consumer electronics, data/telecom, computers, and instrumentation. It can protect a wide range of components, including diodes, DMOS transistors, and other MOSFETs. In addition, it is also suitable for the protection of low-voltage AC and DC circuits. To ensure the best surge protection, the ROV05H471K-2 should be used in combination with other components such as capacitors and resistors.

2. Working Principle of ROV05H471K-2
TVS – Varistors, MOVs are electronic components that can limit the voltage across them. The ROV05H471K-2 is a metal oxide varistor (MOV) that works by diverting the surge current away from the protected device when a voltage spike occurs. In the normal state, the MOV is a passive device with a very high impedance. When the MOV is subjected to a voltage spike, the impedance drops and the MOV starts to conduct more current. The MOV also absorbs the energy of the voltage spike and dissipates it in the form of heat. Thus, the surge energy is dissipated, protecting the components that are connected to the MOV.

The ROV05H471K-2 has a clamping voltage of 38 V and a rated current of 5 A. It also has RoHS compliant termination and is UL94V-0 flame rated. Therefore, it is suitable for applications with high levels of shock and vibration.

In conclusion, the ROV05H471K-2 is a metal oxide varistor that is suitable for protecting sensitive electronic devices from voltage spikes and surges. It has a high impedance in the normal state and a low impedance when a voltage spike occurs, allowing it to absorb and dissipate the surge energy. The ROV05H471K-2 also has RoHS compliant termination and UL94V-0 flame rated making it suitable for high vibration applications.
