MLVA04V18C085-R

The MLVA04V18C085-R, classified as a TVS – Varistor, MOV, is widely used for a variety of applications to provide reliable, surge protection.

A varistor, or voltage-dependent resistor, is an electronic component which acts like a resistor but with a voltage-dependent resistance. It experiences an almost exponential increase in resistance as the voltage drops. As such, it is useful for absorbing transient spikes or pulses of energy. A varistor is essentially a non-linear resistor and has the ability to regulate and limit the voltage when it goes beyond the normal operating voltage.

The MLVA04V18C085-R is an MLV Series General Purpose Radial Lead Varistor designed for AC/DC/impulse surge suppression. It is designed to provide overvoltage protection for a wide variety of electrical components such as: power converters, power supplies, rectifiers and other microcircuits. It is rated for a maximum working voltage of 18V, and a clamping voltage of 85V.

The varistor responds quickly to transient overvoltage spikes, such as those caused by lightning strikes or electrical surges. It has a fast response time to within nanoseconds, allowing it to absorb electrical pulse overshoots before they can cause damage. This makes it useful as reliable form of surge suppression. The varistor also has a low capacitance, allowing it to remain stable when different ground potentials exist.

The MLVA04V18C085-R comes in a 4-pin radial lead package, and operates in temperatures between -40°C to +85°C. It has low noise characteristics and low leakage current levels. The device is designed for AC applications, but also offers high surge protection in both DC and impulse voltage applications. It also has transient surge suppression and line filter capabilities.

The MLVA04V18C085-R is an ideal choice for overvoltage protection and surge suppression in a variety of industrial, consumer, telecom, and renewable energy markets. The device can be used as a direct replacement for any existing MOV or varistor devices, and is capable of handling higher power levels and greater transient peak events than traditional MOV or Varistor components.
