The MLVB04V18C003 is a Varistor product offered by Littelfuse and it has diverse applications and a reliable working principle. In this article, we will discuss the application field and working principle of the MLVB04V18C003.

Applications of MLVB04V18C003

The MLVB04V18C003 is primarily used in high voltage surge protection. It helps to protect electrical and electronic equipment from high voltage transients and sparks that are likely to occur in many industrial and residential power lines. As it is designed to handle higher surge voltages than other conventional products, it is an essential component for safeguarding against threats to expensive equipment in many industries.

The MLVB04V18C003 is also used in the automotive industry for transient protection in automotive electronics and components. It is designed with a low profile so that it can be used in compact engine compartments without impeding the vehicle\'s performance. Other common applications of the MLVB04V18C003 include protection of sensitive data line connectors and mission critical systems in the aerospace, defense, medical and renewable energy industries.

Working Principle of MLVB04V18C003

The MLVB04V18C003 belongs to the set of varistors, metal oxide varistors, or MOVs, which are components that provide protection against transients and surges by limiting the voltage that can pass through a circuit. This protection is achieved through the special electrical characteristics of a varistor, which change when the applied voltage crosses the specified threshold. When the applied voltage crosses that threshold, the resistance of the varistor increases rapidly from a very low to an extremely high value.

The MLVB04V18C003 is designed with metal oxide elements surrounded by zinc oxide which forms the varistor material. The metal oxide elements are triggered when an increase in voltage occurs, sending electron currents to the zinc oxide which in turn causes the resistance of the circuit to increase rapidly. This rapid increase in resistance protects the circuit against transients and surges. When the voltage returns to normal, the resistance slowly declines, allowing the circuit to return to normal operation.

Conclusion

The MLVB04V18C003 is an important product in the area of TVS - Varistors, MOVs. It has a wide range of applications in the industrial and automotive sectors, and its reliable working principle enables it to provide reliable and effective protection against transients and surges. This makes the MLVB04V18C003 a highly sought after product in many industries.
