TVS – Varistors, MOVs devices play an important role in reducing the downstream voltage stress on the various circuits of the system. The V18MLE0603LNH is a varistor device designed to provide excellent over voltage and transient protection over a wide range of voltage and temperature range. This article will discuss the V18MLE0603LNH application field and its working principle so readers can understand how it functions and where it is used.

V18MLE0603LNH Application Field

The V18MLE0603LNH has a working voltage range of 5-300V, making it suitable for a vast range of applications. It is used in power supplies, automotive, electronic circuits, peripherals, industrial or residential applications. It is also used as a protector in communication systems for data lines, signal lines and power lines, and it is also used in lighting protection for railways. The V18MLE0603LNH is designed to protect the load from voltage transients, electrostatic discharges and overvoltage events. It can also be used as an anti-surge and anti-voltage spikes protector which provides an extra layer of protection for the connected devices and circuits. Additionally, it can also be used to suppress high frequency noise from radiating outside of the equipment.

V18MLE0603LNH Working Principle

The V18MLE0603LNH works on the Metal Oxide Varistor (MOV) principle. It is basically a voltage-dependent, nonlinear resistor with increased resistance in normal conditions which drastically lowers its resistance during overvoltage and surge events. The V18MLE0603LNH contains a metal oxide material layer that acts as a semiconductor. When a potential difference is applied between its terminals, the metal oxide layer is biased. This results in a decrease in the resistance, and consequently, large current transfers can occur from the terminal with the higher potential to the terminal with the lower potential.

The V18MLE0603LNH can be beneficial in reducing the destructive impact of voltage overshoots and transients. In normal condition, the V18MLE0603LNH offers a high resistance, so no current will flow until a surge or transient is applied. When an overvoltage situation is detected, its resistance quickly decreases allowing more current to flow and consequently, the overvoltage is quickly clamped and dissipated. The V18MLE0603LNH can provide an excellent level of protection from both steady state and impulse overvoltages for many different electrical systems and equipment. It can also be used to reduce system noise.

The V18MLE0603LNH is a small, reliable and durable varistor device that provides effective protection against overvoltage. Its wide working range, high peak pulse current and its excellent response to transients makes it an ideal choice for a variety of applications where reliable protection is needed.
