CFR-12JR-52-1R3 (Carbon Film Resistors) are seen as a regular Through-Hole Resistors that offer a higher temperature rating than carbon Film Resistor and have a better stability to environmental changes. They are available in the form of 1/8-watt molded axial resistors in an easy-to-use through-hole configuration. This type of resistor generally has a better thermal performance than some other types of resistors, allowing the user to use it at the following temperature range, from -55 ºC to +155 ºC

The Working Principle Behind CFR - 12JR - 52 - 1R3

The design of the CFR-12JR-52-1R3 utilizes a substrate with a carbon film as its resistor material. This is then connected to two metal end caps - one being composed of tin plated and the other having a nickel plated finish. In between these two end caps, the resistor material is stuck into a cylindrical slot. This ensures that the resistor material is able to maintain a fixed position in the substrate, and therefore a very stable resistance value over time.

The working principle of the CFR-12JR-52-1R3 is straightforward. Under an AC or DC current, electrons flow around the substrate, which results in Joule heating. The heat is then dissipated through the end caps, resulting in a decrease in temperature. The heat energy gradually dissipates until the temperature has returned to ambient conditions. In this way, the resistor is able to provide a constant and steady resistance.

Applications for CFR - 12JR - 52 - 1R3

Due to its excellent thermal performance, CFR-12JR-52-1R3 resistors are used in applications where high-temperature conditions exist. They are commonly used in automotive, industrial, and commercial applications. For example, they can be used in power supplies in computers, motor control systems, PCBs, printers, and switchgear. Furthermore, this type of resistor is suitable for application in harsh environment such as in aircrafts, mining, automotive and railroad systems.

CFR-12JR-52-1R3 resistors are also excellent for pulse- and audio-related applications because of their low inductance design. They are therefore perfect for use in audio systems, as they offer low noise, good frequency response, and a fast recovery time. They are also an ideal choice for general-purpose AC and DC circuits.

Conclusion

The CFR-12JR-52-1R3 resistor is an excellent through-hole resistors that have a high temperature rating and good stability to environmental changes. They are also suitable for a wide range of applications, especially for audio circuits, motor control systems, and power supplies. This type of resistor offers an excellent thermal performance and is therefore ideal for use in harsh conditions. With their cost-efficient design and excellent performance, CFR-12JR-52-1R3 resistors are an ideal choice for many applications.
