VAR-18120320M5P-XK application field and working principle

TVS - Varistors, MOVs are commonly used in on-board applications for overvoltage surge protection. The VAR-18120320M5P-XK is especially designed for ESD/EFT/surge and taping lines. The application fields of the VAR-18120320M5P-XK include automotive, medical, military, HVAC, consumer electronics, etc., and it is widely recognized for its superior performance.The VAR-18120320M5P-XK is also known as a varistor. By definition, it is a voltage-dependent, nonlinear, semiconducting device commonly used for overvoltage protection. When exposed to sudden increases in voltage, it will activate and reduce the surge or spike. It acts as a regulator, redirecting the excess current by forming a low impedance path until the surge energy is dissipated. The VAR-18120320M5P-XK is implemented using Metal Oxide Varistor (MOV) technology. This is a two-terminal device that uses metal-oxide layers to dissipate energy during transients. It is constructed from many layers of zinc-oxide grains that are connected in parallel to create a high capacitance device. When triggered by a surge or voltage spike, the MOV will allow the current to bypass the varistor, effectively protecting the circuit from the destructive surge. The MOVs are highly durable due to their ability to absorb and dissipate high surge currents without being damaged.The VAR-18120320M5P-XK has an ultra-low clamping voltage, making it ideal for power line distribution systems. It is also designed with a wide working temperature range, making it suitable for a variety of environmental conditions. Additionally, its self-healing properties provide it with excellent durability. With its small size, the VAR-18120320M5P-XK can easily fit into a narrow board space.Applications of the VAR-18120320M5P-XK include lightning, transient voltage protection for automotive, medical, military, consumer electronics products, and HVAC systems. It is also used for high-speed direct lightning transients made possible by the Varistor’s fast response time. Additionally, the VAR-18120320M5P-XK is ideal for power line distribution systems due to its ultra-low clamping voltage.In conclusion, the VAR-18120320M5P-XK is a Metal Oxide Varistor (MOV) manufacturer with a wide range of applications. It is highly durable, with self-healing properties. Additionally, its ultra-low clamping voltage makes it ideally suited for power line distribution systems. Last but not least, its small size allows it to fit into even the narrowest board spaces.
