Varistors, also known as Voltage Dependent Resistors (VDRs) or Voltage Dependent Semiconductor Devices (VDS), are components which have a non-linear resistance that varies significantly with applied voltages. The ROV10-681K-S-2 is a gas-filled low-capacitance Varistor used for surge and overvoltage protection.

The ROV10-681K-S-2 Varistor is composed of a zinc oxide ceramic core and a state-of-the-art over-voltage protection technology known as PulseGuard. The product has been designed for use in electrical systems where higher peak impulse voltage protection is required. The device has a low capacitance, low clamping voltage and low series inductance, making it suitable for sensitive electronic applications.

The ROV10-681K-S-2 Varistor is suitable for computers, electronic equipment, power systems, control systems, communication systems, industrial equipment, appliance and automotive applications. It is also suitable for use in low power AC/DC systems, with a voltage ranging from DC to 400V.

The ROV10-681K-S-2 Varistor works by providing a high impedance path for transient currents until they start to disturb the normal operating conditions of the protected system. The high impulse current capacity makes it effective in protecting from both lightening surges and fast transients generated within a system. When a surge or transient occurs, the high impulse current capacity absorbs the energy, thus preventing any damage to the system.

The ROV10-681K-S-2 Varistor has several advantages over other methods of surge protection. It provides superior performance with its low capacitance, low inductance and low clamping voltage. Additionally, the device has an extremely low series resistance, allowing for it to be used in applications which require high current. It is also designed with an extremely low thermal coefficient, which helps to ensure enhanced reliability and increased lifetime.

In summary, the ROV10-681K-S-2 Varistor is a high performance, low capacitance Varistor designed for use in surge and overvoltage protection applications. It is suitable for use in a wide range of AC/DC systems and provides superior performance due to its low capacitance, low inductance and low clamping voltage. Additionally, the device has a low series inductance and an extremely low thermal coefficient, allowing it to be used in applications which require high current and enhanced reliability.
