The ROV10H681K-S-2 Varistor (also known as a Voltage Dependent Resistor or just VDR) is a component used to protect semiconductors and other components from high-voltage spikes and one of the most commonly used in today’s electronics. As part of the TVS - Varistors, MOVs family, it has been designed to provide efficient protection against lightning and other transient events.

A Varistor is a voltage-dependent resistor comprised of two or more layers of metal oxide material. When the voltage applied at the terminals of the device reaches its rated value or higher, sudden electrical changes occur, resulting in an increase of the current passing through the device. This instantaneous increase in current is what protects the connected circuitry.

The ROV10H681K-S-2 Varistor is a monolithic device with a wide operating voltage range of up to 9.8V and a maximum operating temperature of 105°C. It is designed to protect against high frequency transients and is well suited for automotive applications. It is a fully encapsulated, pole-mountable device that is compact and easy to install. The device features an integrated pole protection layer which can provide additional safety for the user. It also features an “enable/disable” pin which makes it easy to switch between the protection and power off modes.

Varistors are commonly used in a variety of applications such as automotive, medical, consumer electronics, industrial and communication systems. In automotive applications, they are used to reduce the risk of electrical damage resulting from high-voltage transients. In consumer electronics, they provide protection from voltage spikes, which can damage delicate electronics such as computers and cell phones. In industrial applications, Varistors are used to protect gas-discharge lamps from voltage fluctuations. In addition, they are also used in the telecommunications industry as surge suppressors.

The ROV10H681K-S-2 Varistor works on the principle of electrical over-voltage protection. When a surge voltage is applied to the terminals of the device, it responds by limiting the current that flows through the device. This allows it to protect sensitive and fragile components from over-voltage damage. The device is designed to respond quickly, limiting the damage caused by high-voltage transients. The instantaneously increase in current limits the damage to connected circuitry.

In conclusion, the ROV10H681K-S-2 Varistor is a great solution for protecting sensitive components against high-voltage spikes in a variety of applications. It is specifically designed for automotive applications, and has an integrated protection layer for enhanced safety. With its wide operating voltage range and quick response time, the ROV10H681K-S-2 Varistor is an ideal solution for protecting sensitive components in automotive applications.
