ROV14-821K-2 is a type of varistor with a unique design that has a wide range of applications. It is a two-metal oxide varistor (MOV) that can protect against transient voltages and other kinetic energy disturbances. Additionally, it can also be used to limit the power supply voltage for improved system efficiency and stability.The ROV14-821K-2 has a wide working range, with a maximum operating voltage of 14 V and a maximum operating current of 821 mA. These parameters give the device good overcurrent protection capabilities, allowing it to handle larger current peaks than other MOVs. Due to its robust design, the ROV14-821K-2 is also suitable for applications where high levels of humidity or shock are present.The working principle of the ROV14-821K-2 is based on the Zener effect. When a transient voltage is applied to the device, it dissipates the excess energy in the form of heat. This heat is then dispersed by a thermal dissipation element, such as a heat sink, which prevents the device from overheating. The ROV14-821K-2 is available in a wide variety of packages and can be used in a range of applications.The ROV14-821K-2 is often used in computer systems as transient voltage suppressors (TVS). These devices protect against voltage spikes and other transients that can cause errors or damage to sensitive components. The ROV14-821K-2 provides protection by limiting the voltage to a safe level before it can damage any components.The ROV14-821K-2 is also used to provide overcurrent protection in automotive systems. In these applications, the device limits the current transmission to a safe level, protecting sensitive components from overload and damage. Additionally, the ROV14-821K-2 can be used to protect radio frequency applications from voltage transients, caused by lighting, radio interference, or switching power supplies.In industrial applications, the ROV14-821K-2 can be used as a surge protector, protecting sensitive equipment from electrical transients, such as those caused by power outages or voltage spikes. The device also has a wide operating temperature range, making it suitable for use in both indoor and outdoor environments. The ROV14-821K-2 is an excellent choice for protecting AC/DC systems from potentially damaging transient voltages.The ROV14-821K-2 is a versatile device with multiple uses and applications. This two-metal oxide varistor is an excellent choice for applications that require high levels of transient voltage protection. Not only does the ROV14-821K-2 provide superior overcurrent protection, but it also has a wide operating temperature range and can be used in a range of environments. It is an essential device for any application where transient voltages may occur.
