MOV-20D182K is a type of metal-oxide varistor (MOV), commonly referred to as a transient voltage suppressor. It is designed for overvoltage protection of electrical circuits, preventing damage from lightning strikes and other voltage-related faults. The device consists of a circuit board with multiple disc-shaped varistors and a polymeric material, making it suitable for applications like AC power inputs and output circuits.The working principle of the MOV-20D182K is quite simple; when a sudden increase in voltage occurs, the MOV-20D182K will generate an electric field, which in turn triggers the varistor. This action allows for a rapid decrease in voltage, thus preventing transients or surges from passing through the device. This simple mechanism prevents electrical damage and power outages caused by over-voltage events.The MOV-20D182K can be used in a wide range of applications, including low-voltage DC supplies, rectifier circuits, and flyback power supplies. It is often seen in industrial and commercial buildings, as well as in consumer electronic products, where it is used to protect against voltage surges and transients. The device can also be used in power systems, where it offers enhanced protection against voltage fluctuations, thus avoiding unnecessary outages and costly repairs.The MOV-20D182K comes with a number of features designed to promote better performance and longevity. It is UL-recognized and has a highly flexible design, allowing it to fit a wide range of applications. Also, it has a low capacitance and inductance rating, meaning that transient voltage spikes are minimized and its performance is stable over a wide temperature range. Moreover, the MOV-20D182K has a thermoplastic material that allows it to dissipate heat quickly, enhancing its reliability.In conclusion, the MOV-20D182K is an efficient and reliable solution for protecting against unexpected voltage transients and surges. Its simple but effective working principle, UL-recognition, and flexible design make it ideal for use in industrial and consumer electronics applications. With its low capacitance and inductance rating and thermoplastic heat dissipation, this device from KEMET ensures that your electrical systems remain up and running in the event of unexpected surges.
