Through Hole Resistors are an essential part of the electrical apparatus, as they are responsible for controlling the flow of electricity in order to maintain safe and efficient operation. The UPF25B350RV is a robust and reliable through hole resistor from ExcelsysTech, specifically designed for applications in high voltage circuits.

UPF25B350RV Application Field

The UPF25B350RV is ideally suited for applications dealing with higher voltage, ranging from 4.5kV to 35kV. It offers exceptional performance levels, by providing a higher level of energy efficiency than other through hole resistors. For operation with higher voltaes, the UPF25B350RV also features improved resistance to thermal shock, as well as a shorter recovery time after a fault.

The UPF25B350RV is designed to function in a wide variety of applications, including safety circuits, rectifiers, electrical grid breakdown protection, power supplies, industrial equipment protection, and lightning protection. Other applications include power conditioning in telecom facilities, HVAC systems, power factor correction, and overcurrent protection systems. It is also suitable for use in residential and commercial environments.

UPF25B350RV Working Principle

The UPF25B350RV works by using the principle of electric resistance to limit the amount of current flowing through a circuit. This is accomplished by using two conductors, typically copper wires, which are connected to a semiconductor material. When an electrical current is applied to the circuit, it causes the electrons in the semiconductor material to vibrate, thus creating resistance, which in turn limits the amount of current travelling through the circuit.

The UPF25B350RV has been designed with a higher level of energy efficiency, by using a ‘low resistance’ configuration, which results in a lower amount of power being absorbed, and a longer life span. It is also designed for improved fire resistance, as it is able to withstand higher temperatures for a longer period of time, at up to 180°C in most cases. The UPF25B350RV is most commonly used in areas where ruggedness and reliability are of paramount importance.

Conclusion

The UPF25B350RV from ExcelsysTech is an innovative through hole resistor designed for applications requiring higher levels of voltage. It is capable of withstanding higher temperatures, has improved resistance to thermal shock, ensures a longer life span, and delivers increased energy efficiency. Its rugged construction and reliable performance make it an ideal choice for power supplies, industrial equipment protection, and lighting protection applications.
