Through Hole Resistors

Through hole resistors are a component found in many electrical applications. Their purpose is to provide a resistance to an electrical circuit or signal, allowing for greater control of current flow. The OK2455E-R52 is a popular through-hole resistor manufactured by ABB, designed to provide superior performance and reliability. This article will provide an overview of the OK2455E-R52’s application field and working principle.

Applications Of The OK2455E-R52

The OK2455E-R52 is designed for use in a variety of low voltage applications, such as amplifiers, transducers, and other industrial equipment. It is often used in RF communication circuits, semiconductor based devices, and automotive electronic components. It is also suitable for providing a resistive element in AC and DC power supply applications.

Working Principle Of The OK2455E-R52

The OK2455E-R52 is a through-hole resistor constructed of sturdy, heat stabilizing materials and coated for protection. The resistor is designed to provide a fixed value of resistance for any AC and DC electrical signals. It offers high performance and reliable operation due to its tight tolerance and temperature stability. In order to achieve a specific value of resistance, the resistor has a layer of resistive material between two metal contact layers. When the current flows through the resistor, the resistive material absorbs a certain amount of energy, broken down in the form of heat. This heat will increase the resistor’s temperature, which is why the protective coating is important in preventing any damage. The OK2455E-R52 is able to sustain temperatures 200% greater than its rated power, significantly increasing its life cycle.

Conclusion

In conclusion, the OK2455E-R52 is a reliable, high performance through-hole resistor manufactured by ABB. Its tough construction and protective coating makes it suitable for a variety of low voltage applications, such as amplifiers, transducers, RF communication circuits, and other industrial equipment. It is able to provide a fixed value of resistance and sustain high temperatures without suffering any damage.
