The ROV10-911K-S-2 is a TVS / Varistor / MOV (Transient Voltage Suppressor / Metal Oxyde Varistor / Metal Oxide Varistor) component used to protect sensitive electronic components from dangerous voltage spikes and surges. It has an operating voltage of 16-35V and a clamping voltage of 65V. This device is designed to suppress the peak transient surge current up to 9.1kA in 10/1000μs waveform.

Application Field

ROV10-911K-S-2 is typically used in automotive, military, and industrial systems; particularly those that require reliable protection from voltage transients associated with power lines. It can be used to protect DC-DC converters, automotive circuits, industrial instrumentation, and motor controllers. It is also suitable for applications in the telecommunications and computer industries.

Working Principle

ROV10-911K-S-2 is a non-linear component. It operates essentially on the principle of the varistor material’s resistance to a voltage change. The material has two distinct voltage levels where the resistance between them is sharp. Below the lower level, the resistance is relatively high, whereas, above the higher voltage, the resistance drops drastically. This characteristic causes the ROV10-911K-S-2 to limit the current when it experiences a surge above the higher voltage limit, thus protecting the application system.

In operation, when the ROV10-911K-S-2 is exposed to a voltage surge that is higher than its clamping voltage, it resists the current passing through it and limits the voltage to below the device’s clamping voltage level. As the surge current passes through the device, the voltage rises in an exponential manner, then levels off and eventually decreases. Once the surge has passed, the component returns back to its normal operating state.

In summary, the ROV10-911K-S-2 is a TVS / Varistor / MOV component designed to provide reliable protection from voltage transients associated with power lines. It works on the principle of the varistor material\'s resistance to a voltage change, limiting the current when the component experiences a surge above the higher voltage limit and providing protection to the application system.
