A varistor is an electronic component that is used to provide surge protection for electrical and electronic systems. It has a high resistance-to-voltage ratio, allowing it to respond quickly when presented with an overvoltage transient. The ROV14-181K is a varistor manufactured by Littelfuse that provides voltage suppression when applied to an external circuit. It features a wide range of AC or DC energy absorption levels, allowing for effective protection of a variety of consumer and industrial applications.

The ROV14-181K varistor is a encapsulated, disk-shaped, metal oxide varistor composed of zinc oxide, aluminum oxide, and silicone oil. It is designed for a variety of electrical applications including uninterruptible power supplies, computers, machinery, communication systems, and circuit protection devices. The device has a rated voltage of 14 VDC, a clamping voltage of 181 VAC, and a maximum energy of 10 joules. It is available in a range of sizes, from 4 mm to 10 mm.

The working principle of the ROV14-181K varistor is based on the zener diode theory. The device has two leads that connect to the two terminals of the diode. When an overvoltage transient occurs, the device’s response is to clamp the voltage at the set level, resulting in energy absorption and protection of the external circuit. As the overvoltage transient increases, the varistor reacts by increasing its resistance, allowing for greater energy absorption.
