Transient Voltage Suppressors (TVSs) are electrical components that are used to prevent damages to electrical systems due to sudden surges in voltage. These devices come in many different varieties, including Varistors, Metal Oxide Varistors (MOVs) and Zener Diodes. ROV10H391K-2 is a specific type of MOV which is particularly useful for protection against lightning and other transient voltage events. This article will cover the application field and working principle of this type of TVS.

Applications Field of ROV10H391K-2 MOV

ROV10H391K-2 MOVs are designed to provide robust protection against transients, surges, and high-voltage spikes. They are especially useful in applications that require protection from lightning strikes, as they can handle large amounts of surge energy. The ROV10H391K-2 MOV has a maximum clamping voltage of 807V, so it can protect electronic devices from spikes up to this voltage. Furthermore, it has a low let-through voltage of 81V, so it can provide protection even when the input voltage is already high. Due to its high energy tolerance, the ROV10H391K-2 MOV is often used in industrial applications such as power supplies, automotive systems, and data transmission systems.

Working Principle of ROV10H391K-2 MOV

ROV10H391K-2 MOVs are metal oxide varistors that work by clamping the input voltage to a safe level when a transient voltage spike occurs. When the MOV is subjected to a high voltage, it acts like a resistor whose resistance is determined by the metal-oxide film on its surface. This film has a resistivity that varies with voltage. Thus, when the voltage exceeds a certain level, the resistance of the MOV increases to a point where it no longer allows the voltage to exceed a certain level, thereby preventing damage to the connected devices. In this way, the MOV acts as a surge protection device.

The ROV10H391K-2 MOV also has excellent temperature stability. This is achieved by using an enhanced thermal stability technology which utilizes a specially designed metal oxide film. This technology ensures that the MOV\'s electrical properties remain stable even when the temperature changes. The MOV\'s clamp voltage remains stable over a wide temperature range, which makes it an ideal choice for applications that require reliability in harsh environments.

Conclusion

ROV10H391K-2 MOVs are highly effective transient voltage suppressors that can provide reliable surge protection in industrial and automotive applications. They are capable of handling high amounts of energy, while still maintaining a low let-through voltage. Furthermore, they feature an enhanced thermal stability technology which ensures that their electrical properties remain stable over a wide temperature range. Thus, ROV10H391K-2 MOVs are an excellent choice for applications that require reliable surge protection.
