TVS - Varistors, MOVs, specifically ROV05-471K-2 type of devices, are widely used in various fields including power supply, various automatic controls, and different telecommunications systems and networks. These devices are essentially a kind of voltage dependent resistor, i.e. a semiconductor device containing a metal oxide layer that acts as an ionic insulating barrier and a number of closely spaced semiconductor layers.

The advantage of ROV05-471K-2 is its low capacitance, the low clamping voltage, and the high dv/dt value. In addition, the device ensures excellent EMI/RFI noise suppression (in the range 10K-150KHz). As for the working principle of ROV05-471K-2, it is the controlling mechanism of current conduction, which is based on the idea of the zener diode. In fact, when the voltage is greater than the rated voltage, these devices will turn on and form a low resistance conduction path. The voltage across the MOV will be limited to the device\'s rated value and the current passing through it will be minimized.

Nowadays, applications of ROV05-471K-2 such as low-pass filter, capacitor charging circuit, line decoupling, and power converter circuit are increasingly being used in a wide range of industries. In low-pass filter, it helps to reduce the ripple in power supply line and improve the efficiency of power source by suppressing the EMI noise. Moreover, it is used in capacitor charging circuit to decrease the charging time and improve the capability and stability of charging process. In line decoupling, these devices protect the sensitive circuits from the objective damage from the hostile environment and also protect them from the high voltage spikes. Last, but not least, it is able to maintain the stability of power converter circuit working function. Moreover, it helps to minimize the noise generated in power conversion process and adapt the ripple in power switching process.

Overall, ROV05-471K-2 is a kind of versatile electrical device with low leakage current and many advantageous characteristics. In addition to its multiple application fields, it is also able to work effectively and safely in various hostile environment. Consequently, it is safe to say that ROV05-471K-2 is a device that offers cost-efficiency, reliability and safety for its operator.
