V18MLN41206WH application field and working principle TVS - Varistors, MOVs are commonly used components in electrical engineering. They help protect the circuits in devices from over-voltage and over-current, as well as providing frequency-dependent protection to the circuit as needed. The V18MLN41206WH is one such component manufactured by Vishay. It is a multi-level varistor with high surge protection capability. The component is designed specifically to protect against inrush current, which can cause damage to circuitry, as well as protect against over-voltage/over-current.The V18MLN41206WH is a Surface Mount Devices (SMD) radial-leaded varistor. The component is made up of eight rectangles, which represent eight separate levels of protection. This makes it highly customizable and versatile depending on the needs of the circuit. The varistor is able to provide a wide range of voltage and current protection thanks to its wide range of levels.The component is made up of an internal metal-oxide semiconductor (MOS) surrounded by a ceramic body. This MOS creates a depletion region which redirects the current. As the current increases, the voltage across the MOS increases, creating a barrier to the current that can be adjusted via the rectangles. The rectangles on the V18MLN41206WH interact with the depletion region, allowing for a range of voltages and current values that the component can accurately handle.In addition to its adjustable protection levels, the component has a low leakage current and high aspect ratio, meaning it can provide higher levels of protection than a traditional MOV. It also contains a “soft terminal” design which helps reduce the risk of arcing, which is often seen in other MOVs. The addition of these features makes it a more reliable and safe protection device.The V18MLN41206WH can be used in a wide variety applications, such as telecommunications, industrial, consumer, automotive, and data communications systems. Thanks to its high surge protection capability and multiple levels, it can provide reliable over-voltage/over-current protection in all of these applications.In summary, the V18MLN41206WH is an excellent choice for those needing reliable over-voltage and overcurrent protection. Thanks to its adjustable multi-level protection levels, its ability to handle high surge protection levels, its low leakage current, and its “soft terminal” design, it can be used in a wide variety of applications. These features make it an excellent choice for anyone looking for reliable and up-to-date TVS - Varistors, MOVs protection devices.
