VE07P00151K is a series of Varistors (Voltage Dependent Resistor – VDRs) that are a type of surge protection component used to protect sensitive electronics. Varistors have high surge absorption capabilities compared to other forms of surge protection devices, and are often used in applications where higher levels of protection are needed, such as lighting equipment, communication systems and high-voltage power supplies. As such, they are often employed as an effective form of surge protection for a variety of industrial, commercial and consumer applications.

In order to understand the general application field and working principle of VE07P00151K, it is important to first establish an understanding of Varistor technology. Varistors are non-linear, negative temperature coefficient (NTC) resistors that are made from a solid, sintered ceramic material containing zinc oxide, along with other metal oxides such as cobalt, manganese and nickel. This material exhibits a unique electrical phenomenon known as the “Varistor effect”, whereby the electrical resistivity of the material is dependent on the applied voltage, governed by the Voltage-Current (V-I) Characteristic. In other words, when a voltage potential is applied across the material, a corresponding amount of current is allowed to flow through it. This phenomenon is useful in surge protection applications, since it allows Varistors to absorb and limit excessive current to values that a circuit can safely handle.

A quick overview of the V-I curve of a Varistor is helpful in understanding its working principle. The V-I curve is a graph showing the amount of current that flows through the Varistor at different applied voltages. An example of a typical V-I curve for a Varistor is shown below:

As can be seen from the above graph, the amount of current that flows through a Varistor is inversely proportional to the applied voltage. This means that when the applied voltage is greater, then the current that can flow through the Varistor is lower, and vice versa. Thus, when an excessive amount of voltage is applied, the Varistor is able to absorb it by diverting the current away from the circuit, thus protecting it from overvoltage. A typical Varistor has a working voltage range between 25V and 1500V, and can handle current up to 2000A.

The VE07P00151K series of Varistors is offered in two different configurations; the NTC-I (Negative Temperature Coefficient – Insulated) type, and the NTC-U (Negative Temperature Coefficient – Uninsulated) type. Both types are designed to provide surge protection to sensitive electronic devices, such as computers, televisions and other sensitive electronic systems. The NTC-I type is designed for higher voltage protection, with a maximum rated voltage of 1500V, while the NTC-U type is designed for lower voltage protection, with a maximum rated voltage of 25V. Both types are designed to protect against transient overvoltage and current spikes by providing short-circuit protection. The NTC-I configuration also offers over-temperature protection.

Overall, the VE07P00151K series of Varistors offers superior surge protection compared to other types of surge protection components, and is ideal for applications where higher levels of protection are needed. Their wide range of voltage and current ratings make them suitable for a variety of industrial, commercial and consumer applications. Plus, their compact size and easy installation process makes them a great option for customers who need to quickly and easily install surge protection devices.
