FCR-25JR-52-820R

Through-hole resistors are the epitome of the long- standing application of resistors in electrical engineering. The FCR-25JR-52-820R is a through-hole resistor, which is most commonly used in a variety of electronic circuit types. This resistor is of a fixed, discrete type, meaning that the value of resistance does not change once the resistor is put into place. This article will explore the working principles and application fields of the FCR-25JR-52-820R resistor.

Overview

The FCR-25JR-52-820R through-hole resistor is composed of a small ceramic insulating body material of a predetermined dimension and a selection of resistor elements that can be connected inside depending on the required value of the resistance. This type of resistor is ideal for applications where greater power dissipation and spacing of components is needed. This model offers superior thermal characteristics than surface mount resistors and its bigger size makes it easy to manage. It also provides the user with the convenience of having a bundled unit with mounting screws that can easily be inserted into the designated circuit positions.

Working Principle

The working principle behind the FCR-25JR-52-820R resistor is that of a resistive element. An insulating body of predetermined dimensions is used as the substrate for the resistive layer. The resistive material is then applied in a predetermined pattern across the body with the subsequent connection of the components forming the electrical circuit. The FCR-25JR-52-820R features a variety of different resistive materials with higher tolerance than other types of through-hole resistors, thus offering enhanced performance.

There are three types of resistive elements commonly used in the FCR-25JR-52-820R resistor design. The first is a wire wound type, which features a coil of wire that is wound around a shaft. The resulting circuit offers higher values of resistance than other types of resistor due to the extra length of the wire. The second type of resistor is composed of strips of resistive material, commonly known as zig-zag, which are arranged in a pattern that makes up the electrical circuit. The third is a thin film type, which uses a semi-conductor material as the resistive layer. These thin films are arranged in a series to form the required circuit.

Application Fields

The FCR-25JR-52-820R resistor is most commonly used in low voltage and current application due to its superior thermal characteristics. Its ease of installation makes it perfect for applications that require quick and easy installation such as alarms, security systems and medical devices. Additionally, its robust body and excellent performance make it one of the best choices for intense environments such as automotive applications, where it is used for heating, cooling, and electrical control systems. Other popular use cases for this resistor include power supplies, solar panel regulators, LED lighting and general electrical applications.

Conclusion

The FCR-25JR-52-820R is a through- hole resistor, which is composed of a ceramic body and a number of resistive elements. Its superior thermal characteristics and ease of installation make it a great choice for low voltage and current applications such as those found in medical devices, LED lighting, power supplies and more.
