0072.4281.B1

The 0072.4281.B1 Varistor or Metal Oxide Varistor (MOV) is a voltage-dependent resistor with an electrical characteristic that provides a non-linear, temperature-independent protection against transient overvoltage. Varistors are electrical components that come in a variety of categories and form factors that make them suited to a wide range of applications. Varistors are generally composed of a variety of metals, some of which are highly reactive, which allows them to act as a conductive surge protector and protect critical circuits from damage due to voltage spikes.

Varistors can be made from Metal Oxide materials, such as Zinc Oxide or Silicon Carbide, both of which are commonly used in MOVs. The 0072.4281.B1 Metal Oxide Varistor is a Zinc Oxide-based Varistor and has a Rated Voltage of 250V, a Voltage Range of 30 to 358V, and a Leakage Current of 8mA. It is rated with a Maximum Continuous Operating Voltage of 250V and a Maximum Peak Pulse Voltage of 481V. Additionally, it is rated with a Maximum Clamping Voltage of 480V.

The 0072.4281.B1 Varistor is a voltage-dependent surge protection component. It works by limiting the amount of voltage that can be passed to a protected device, allowing it to withstand an overvoltage that would otherwise destroy it. In most cases, the Varistor will conduct low-level currents, but will shut off when it detects a voltage level higher than its designed maximum operating voltage. When the incoming voltage level exceeds the Varistor\'s leakage current rating, the Varistor will clamp or limit the peak voltage to a value below the breakdown voltage.

Varistors such as the 0072.4281.B1 are generally used in a wide variety of applications, including automotive, aerospace, medical, and industrial applications. They are used to protect sensitive circuits from voltage transients, as well as to provide EMI/RFI noise filtering. They can also be used for overvoltage protection, ESD protection, and overload protection. Furthermore, Varistors can be used to dampen short-term voltage spikes, providing a smooth transition between voltage levels.

The 0072.4281.B1 Varistor is a particularly convenient choice for those who have a need for a Metal Oxide Varistor in a limited form factor. Its relatively low leakage current makes it suitable for a variety of applications, and its wide voltage range allows it to protect a variety of connected devices. As a result, the 0072.4281.B1 Varistor is an ideal choice for those who require a compact Varistor that is capable of protecting a range of devices from overvoltage.
