TVS – Varistors, MOVs have various types, and ROV14-621K-S is one of them. It is a high power, axial-lead varistor, suitable for overvoltage circuit protection, and it belongs to the 14 series. This type of protection component has a wide range of applications in various industries, and its working principle is simple yet efficient.
Firstly, let’s look at the application field of the ROV14-621K-S. This type of varistor has a 350VDC maximum working voltage, which makes them suitable for a wide variety of applications. In addition, it has a surge current withstanding capability of 400A, making it an ideal component for overvoltage circuit protection. This type of protection component is widely used in the industrial, aerospace, defense, and medical industries. In the aerospace industry, for example, this type of product is used extensively for undeflight power failure protection and lightning protection. In the medical industry, this type of protection component is used for patient-related safety circuits, such as cardiovascular, endovascular, and pacing therapies.
Now, let’s look at the working principle of the ROV14-621K-S. It works by using the metal-oxide varistor (MOV) principle. When exposed to voltage, the MOV literally becomes highly conductive and passes the current along desired pathways. This helps protect delicate electronic components from overcurrent and overvoltage surges, which can damage circuits and cause them to malfunction. In addition, it also helps protect against electrical noise, which can also damage sensitive circuitry.
The ROV14-621K-S, like other types of varistors, is used to provide overvoltage and overcurrent protection. It works by using the MOV principle, where a metal-oxide layer is used as a semiconductor conductor. When the voltage exceeds the rated voltage, the MOV rapidly becomes conductive and thus passes the surge of current down the desired pathways, protecting the delicate circuitry within. In addition, the MOV can also provide noise-dampening effects, further protecting sensitive circuitry.
In conclusion, the ROV14-621K-S is an axial-lead varistor suitable for overvoltage circuit protection, and it belongs to the 14 series. It has a wide range of applications in various industries, and its working principle is simple yet efficient. It works by using the metal-oxide varistor (MOV) principle, where a metal-oxide layer is used as a semiconductor conductor. When exposed to voltage, the MOV rapidly becomes conductive and passes the surge of current down the desired pathways, protecting the delicate circuitry within. It also helps protect against electrical noise, which can also damage sensitive circuitry.
