TVS - Varistors, MOVs

The ROV14H180M is a silicon-based device, commonly referred to as a Metal Oxide Varistor (MOV). It’s designed to provide protection against transient voltage surges, and is used in a wide range of applications. The MOV is able to absorb large amounts of energy, providing greater support and resilience against electrical transients than regular varistors, as well as giving the MOV longer life time characteristics which are highly valued.

The core technology behind the ROV14H180M starts with its construction of multiple metal oxide discs which are stacked between two printed circuit boards. These discs are surrounded with a metal casing. The discs themselves are made of a zinc oxide-based ceramic material which serves as a capacitor during normal operation, and a resistor during transients. This allows the device to temporarily absorb large amounts of power, removing the load from the power line, and providing protection against any further transients.

An advantage of using the ROV14H180M is its ability to have consistent, repeatable performance and the potential for customization by changing its size, resistance, and capacitance ratings, as well as having multiple mounting options. This makes them ideal for a variety of industries, including automotive, telecommunication, industrial, computer/smart device, and consumer-level applications.

The ROV14H180M is normally used in conjunction with a Voltage Dependent Resistor (VDR) or Transient Voltage Surge Suppressor (TVSS) and an AC Line Filter or Input / Output Filter. The combination of these three components provides a complete package for protecting sensitive electronics from transient voltage surges. It is important to note that when such a system is implemented, the MOV must be the first component in the chain and must be properly grounded for optimal protection.

It\'s important to select the right Metal Oxide Varistor for your particular application as they come in many different sizes, ratings, and configurations. For automotive applications, the ROV14H180M will be used to protect against reverse battery events or when a battery is reversed, a condition which is becoming increasingly more common with the advent of newer types of power converters.

For industrial control systems, the ROV14H180M is designed to absorb transients from motor induction, electrical arc-welding, and even lightning strikes. In the case of lightning, the device is designed to protect circuits from high-energy pulse of energy or spikes of electricity which are known to cause significant damage. Telecommunication and computer equipment benefits from MOV protection through providing protection from spikes which often occur when power lines cross or equipment grounds, overvoltage conditions, and other forms of power errors or interruptions.

In summary, the ROV14H180M is a state-of-the-art and trusted device which can be used for a variety of applications. By providing an extra layer of protection, the MOV is able to protect sensitive electronics from electrical transients and provide a much longer life time than the average varistor.
