Varistors, also known as voltage-dependent resistors (VDRs), are important components in electronic circuits. They are components that can absorb and dissipate energy in the form of electrical pulses. A varistor commonly consists of semiconductor material with a large amount of mainly zinc oxide combined with a variety of other metal oxides. It possesses a nonlinear electrical resistance that varies linearly with the voltage applied across it, offering overvoltage protection. MOVs, or Metal Oxide Varistors, are also known as surge suppressors and protect electronic device circuits from voltage spikes. They act as a shunt that diverts shock energy away from sensitive components and dissipates it as heat. The V18MLE1206WT is an unencapsulated disc metal oxide varistor (MOV) designed for use in surge and transient voltage protection.

The V18MLE1206WT Varistor has a maximum rated AC voltage of 180VAC and can handle a range of surge voltages up to 24V. It has an operating temperature range of -40 to 85oC, with an insulation resistance of greater than 100MΩ and DC sparkover voltage up to 28V. The flashover, or maximum transient voltage, of the V18MLE1206WT is 1450V, with a voltage-temperature coefficient of less than 0.39KV/K. This varistor has also been designed with an overvoltage protection for ground noise suppression.

The V18MLE1206WT application fields are wide and varied. This device can be used to protect various electronic circuits, such as high-end intelligent meters, PLC-related products, communications products, power products, audio/video products, home appliances, automobiles, and other electronic products. It can also be used for overvoltage surge protection in solar LED lighting systems or other solar power systems.

The working principle of the V18MLE1206WT Metal Oxide Varistor lies in its ability to absorb electrical pulses and dissipate the energy as heat. When the applied voltage across the device is below its rated voltage, current flows through the circuit normally. When a surge or transient voltage occurs and exceeds its rated voltage, the varistor begins to conduct more current, thus protecting sensitive components from damage. As the current flows, the generated heat dissipates, maintaining the device within safe operating temperatures.

The V18MLE1206WT is an unencapsulated, disc-shaped varistor, making it ideal for cost-effective protection in small spaces. The metal oxide material used gives the device high surge capabilities with low leakage current characteristics. Additionally, its small size and high energy capabilities are perfectly suited for use in various consumer electronics. The varistor’s fast response time protects the device and connected components from overvoltage before damage can occur.

The V18MLE1206WT is both reliable and easy to use and can be applied in a wide range of different fields. It offers robust and cost-effective surge protection for a variety of electronic circuits. Additionally, its small form factor and minimum footprint make it ideal for applications requiring reliable surge protection with a small form factor.
