TVS - Varistors, MOVs

The ROV10H241K-S is a type of Varistor or Metal Oxide Varistor (MOV) which is commonly used in the field of overvoltage protection. This type of device is used to absorb and divert electric surges, providing protection against power surges and other overvoltage events.

Varistors are a class of non-linear resistors, more specifically, they are voltage-dependent resistor devices. They are made up of two surfaces: a metal-oxide layer and a junction layer. A varistor is manufactured by combining a ceramic material (sintered zinc oxide) with a metallic layer. The combination of these materials creates a semiconductor bridge, allowing for electrical conduction. The characteristics of a varistor are dependent on the materials used in their construction, most often zinc oxide, along with a variety of other oxides, such as titanium, strontium, and manganese.

The ROV10H241K-S has a varistor voltage rating of 240V AC, meaning that it can absorb voltages up to this level without any damage being done to the device. Varistors are designed to have a relatively large resistance when subjected to low-level voltage inputs, but when higher voltage inputs are applied, the resistance decreases suddenly. This characteristic, known as the nonlinear resistance characteristic, is what allows Varistors to effectively absorb and deflect electrical surges.

Varistors are commonly used in a wide variety of industrial, residential and commercial applications. Common uses include protecting electrical circuits from overloads, overvoltages, and electrostatic discharge (ESD). They are also used to protect sensitive electronic components from transient voltages.

The ROV10H241K-S Varistor is a very reliable device with excellent electrical characteristics. It has an energy absorption capacity of 83J and a maximum breakdown voltage of 420V. It is made with a sintered zinc oxide element, and has built-in overvoltage protection. Its thermally-stable design is capable of dissipating heat effectively, providing superior overvoltage protection.

The ROV10H241K-S Varistor is a very useful and versatile device for many overvoltage protection applications. It is easy to install and provides reliable protection against overvoltage events. Additionally, its thermally-stable design ensures effective thermal management, extending the life of the device and providing excellent overvoltage protection.
