ROV10-471K-S

Transient voltage suppression (TVS) devices are widely used components in electronic products to protect the circuit from overvoltage and high-impact transients. TVS devices come in different sizes and shapes, depending on the application. In particular, the KRI ROV10-471K-S is a small, surface mounted device designed to protect circuit systems from overvoltage transients. With a breakdown voltage of 471V, the ROV10-471K-S is especially useful for applications that require strong surge protection.

The ROV10-471K-S belongs to a class of TVS devices called metal oxide varistors (MOVs). MOVs are components made of zinc oxide or other metal oxides, and they can be a cost-effective way of providing surge protection in a number of systems. Unlike other similar devices, MOVs can provide both clamping and current limiting functions. They also do not require a separate capacitor or inductor for operation, making them an efficient protection choice for certain applications.

The working principle of a MOV is fairly straightforward. When the voltage across its terminals exceeds a certain threshold – the threshold being the device’s breakdown voltage -- current is allowed to flow through the device. The current flow is limited by the conductivity of the metal oxide material, which limits the amount of current that can pass through the device. This helps to protect the circuit from damage caused by high-energy transients.

When deployed in an application, the ROV10-471K-S can help reduce the risk of damage to sensitive electronic components. When the voltage reaches 471V, the device begins to conduct excessively, thus limiting the amount of current that can pass through it. As a result, the surge current is reduced and the system is protected from any possible damage. The device also has a peak power rating of 875W, making it well-suited for high-voltage, high-intensity applications.

The ROV10-471K-S is a reliable overvoltage protection device that can be used in a wide range of applications. Electrical systems such as power supplies, electrical motors, and control circuits can benefit from its excellent surge protection, as can automotive, communications, and industrial electronics. Furthermore, it is small and inexpensive, making it suitable for both high-power and low-power circuits.

In conclusion, the KRI ROV10-471K-S is an excellent low-cost, high-performance metal oxide varistor designed for overvoltage protection. Its small size, simple design, and effective protection capabilities make it an ideal choice for a variety of applications. With its superior surge protection, the ROV10-471K-S is a reliable and cost-effective way to safeguard sensitive electronic circuits from overvoltage transients.
