SMD Varistors

SMD varistors, or Surface-Mount Device varistors, are frequently used in circuits where other types of components may not be suitable. These varistors protect devices from potentially damaging voltage surges. The operating parameters of these components can vary significantly, so it's crucial to know what features to consider when purchasing an SMD varistor.

What Are SMD Varistors?

SMD varistors are components used to ensure the safe operation of electrical and electronic equipment. These components exhibit nonlinear resistance. This means that their resistance drops sharply when the voltage exceeds a specified level set by the manufacturer. This characteristic is particularly useful in designing various devices. SMD varistors absorb energy during sudden voltage spikes, protecting the equipment from failure or damage.

Applications of SMD Varistors

SMD varistors have a broad range of applications. They are among the components used by manufacturers to protect against malfunctions caused by sudden voltage surges. Unlike through-hole varistors, SMD varistors have a different construction and mounting type, allowing them to occupy less space. This makes them ideal for circuits that require protection but cannot accommodate larger components.

How to Choose the Right SMD Varistor

To ensure that SMD varistors perform their protective function effectively, they must be properly matched to the needs of the specific circuit. Before purchasing, it's essential to check the fundamental parameters of the component, such as the varistor's voltage rating, as well as the maximum AC and DC voltage. For SMD varistors, the dimensions of the package are also often crucial. Our store offers components in various sizes, making it easier to find a part that fits your specific requirements.
