ROV07-220L-2

A varistor, also known as a Voltage Dependent Resistor (VDR), is an electronic component with a nonlinear electrical resistance. Varistors are most commonly used to protect circuits against voltage spikes that may occur due to variable power supplies or transient overvoltage events. MOVs, or Metal Oxide Varistors, are a type of varistor specifically designed to absorb large electrical pulses that have an energy of 1 joule or greater. The MOV has become a popular choice for surge protection due to its ease of use and relatively high surge current capability.

ROV07-220L-2 is an MOV designed specifically for automotive and general-purpose applications. The ROV07-220L-2 has a DC voltage rating of 220V and a transient overvoltage (TO-220) rating of 600V. This MOV is capable of absorbing energy up to 5 joules. It also has a high temperature endurance of up to 125°C.

The ROV07-220L-2 is most commonly used in automotive applications to protect circuits from transient overvoltage events. In this application, the MOV is typically placed across the power supply and ground lines as a protective element, with the protection threshold set at the DC voltage rating of the MOV. This allows for a maximum voltage spike of 600V to be handled by the MOV, while the rest of the circuit is still protected from dangerous overvoltage events.

The working principle of the ROV07-220L-2 is based on the nonlinear electrical resistance of the MOV. When a voltage spike occurs, the resistance of the MOV suddenly increases, limiting the amount of current that can flow through the circuit. This protects the rest of the circuit from damage caused by a too large of a current.

The ROV07-220L-2 is a cost-effective and reliable solution for transistor overvoltage protection. Its high temperature endurance and low profile make it suitable for automotive and general-purpose applications. The MOV is easy to install and use, making it a popular choice for surge protection.
