TVS - Varistors, MOVs - is a surge protective device that is effective for impulse protection, employed in different industry fields. One of them is the ROV14E331K-2 varistor, an element designed for use in power lines for the purpose of protecting against transient overvoltages, commonly known as "surges". Designed to withstand even incredibly strong voltage spikes, it has become a popular choice for many organizations.

ROV14E331K-2 Varistor is made mostly of ZnO (zinc oxide), which is the material that gives its overvoltage protection properties. This is a monolithic, non-linear element whose voltage-current characteristics construct a voltage limiting curve. Without any overload, it can be used as a direct power line protector, however, it can also be used in dual in-line assembly, for swift negative pulses or high frequency transient suppressor, depending on the situation.

As far as its applications, it has various field of use in different industries like electronics, telecommunications and computers, also, in transportation, aerospace and military designs. Its most common use is on commercial and industrial power lines, but many other applications benefit from its strength as well.

ROV14E331K-2 Varistor is an excellent choice for all ESD protection since it has an extremely fast response time of less than 1ns, and an impressive 1000A crest allow current rating. This make its total energy absorption capacity of up to 4J, perfect for many pulse protection needs in numerous different applications.

Regarding the working principle, when connected to the power line, the non-linearity of the varistor causes a displacement of the electric current, when the overvoltage exceeds the breakdown voltage, and the current be redirected into the diverting structure. By doing so, the power line reaches a maximum amount of current regardless of any overvoltage.

Principally, the ROV14E331K-2 Varistor can support a maximum current of 40A and withstand a peak pulse voltage of 330V. Besides that, it’s designed to provide superior noise interference protection from AC power distribution lines, resulting in a cleaner DC power supply.

In conclusion, the ROV14E331K-2 Varistor is an extremely reliable and fast-acting device, that is designed to protect your equipment against severe voltage surges, so the production process, or the finished product, can remain intact.
