VC1812K801R014 Application Field and Working Principle

The VC1812K801R014 is a type of overvoltage protection device. It is commonly referred to as a TVS (Transient Voltage Suppression) device, MOV (Metal Oxide Varistor) or simply a varistor. Varistors are commonly used in many types of equipment to protect against transient voltage spikes and surges, and are available in several different sizes to suit the required application. The VC1812K801R014 is an 18mm diameter disc varistor, with radial leads. It is specifically designed for transient voltage protection applications, such as automotive, consumer, industrial, telecommunications and computer and other electronic equipment. The VC1812K801R014 has a non-linear voltage vs. current response. When a high voltage passes through the device, the current is limited due to the increased resistance caused by the non-linear response of the varistor. This effectively provides over-voltage protection to the connected circuitry, as it limits the current to a level that the connected circuitry can handle.It is important to determine the expected surge currents and peaks when selecting a varistor. Depending on the size and type of the varistor, some are able to handle higher surge currents and peak voltages than others. The VC1812K801R014 is constructed of multilayer ceramic di-electric material. It is a metal oxide varistor, which means it is composed of zinc oxide which is compressed to form a monolithic block. The zinc oxide provides the non-linear resistance which limits the current flow when a surge is detected. The VC1812K801R014 has a maximum working voltage of 801V, and a maximum energy absorption of 200J. It also has a maximum surge current of 60A (8/20μs) and a maximum operating temperature of 85°C. The VC1812K801R014 is designed to provide over-voltage protection from induced over-voltage spikes, as well as direct voltage transients. When choosing a varistor for a specific application, the working voltage and peak surge current should be carefully considered to ensure that the chosen device is able to provide the desired level of protection.The VC1812K801R014 provides superior performance in many types of equipment. It is designed to protect equipment from the damaging effects of over-voltage transients. In addition, the VC1812K801R014 is equipped with integral radial leads which enable easy assembly and ensure a secure connection to the equipment. The VC1812K801R014 is also a ROHS compliant device, ensuring that it has been manufactured in compliance with environmental regulations.In conclusion, the VC1812K801R014 is a type of TVS device, protecting connected electronic equipment from over-voltage transients. It is an 18mm diameter disc varistor, with radial leads, which is specifically designed for over-voltage protection applications. The device has a maximum working voltage of 801V and maximum energy absorption of 200J, along with a maximum surge current of 60A (8/20μs). The VC1812K801R014 provides superior performance in the protection of equipment from transient voltages.
