TVS – Varistors, MOVs, are used as an effective way to protect the electronic devices from overvoltage transient, usually caused by lightning. ROV20E201K-S, which is one of TVS – Varistors, MOVs, is a surge absorber and surge suppressor composed of metal oxide and is typically contained in the case. It has excellent surge absorption and energy dissipation capability. The working principle of ROV20E201K-S is that it is designed with a high number of microscopic layers of metal oxide, which divides the dielectric into very thin layers. When voltage is overloaded, the metal oxide layers brake down and accumulates excessive electrons.

ROV20E201K-S has a wide range of application fields. It is specifically designed for protecting data line circuits and sensitive electronic devices against surge, overvoltage currents and clamping voltages caused by energy surges, such as electromagnetic waves, lightning and so on. It is widely used in communication systems, networking devices, personal computers, game consoles and office automation systems. In addition, it can also be widely utilized for industrial, military, automotive, personal electronic products, medical industry and other electronic products.

Besides its application fields, the working principle is also very important here. The ROV20E201K-S working process consists of two stages; the first stage is the clamping stage. In clamping stage, the device will be clamped with overvoltage transient and then it will be passed the current through its resistor layer to the ground. The second stage is the controlling stage. The internal resistor layer of ROV20E201K-S will control the voltage to prevent the damage to the connected devices. Thus, it can protect the electronic devices from overvoltage transient.

Moreover, ROV20E201K-S realizes the high capacitance with its large area. It also has some excellent features such as high current carrying capability, fast response time and low temperature dependence. Therefore, it can provide protection against high-frequency signals and disturbing noises. Moreover, it reduces the chance of false triggering and thus, it is able to reduce the maintenance cost.

In conclusion, ROV20E201K-S is a highly efficient surge absorber and surge suppressor with a wide range of application fields. The working principle of ROV20E201K-S relies on its unique design with a high number of metal oxide layers, which helps to significantly reduce damage to connected electronic devices caused by overvoltage. Through its operation stages and features, it is able to protect electronic devices against high-frequency signals, surges and overvoltages. Therefore, it is widely used in many areas such as communication systems and other personal device protection.
