CFR-50JR-52-240K

Through Hole Resistors are essential building blocks in electrical and electronic circuits. A through hole resistor whose designation is CFR-50JR-52-240K is one of the most commonly used resistors in current market. To better understand the use of this kind of resistor, it is necessary to know its application field and working principle. 

Application Field

CFR-50JR-52-240K mainly find its application in the industry of home electronics and consumer products. Because this type of resistor has reached the requirement of RFI performance, it has a wide application field from the small remote control device to the medium sized electrical motors. Another impressive feature of the CFR-50JR-52-240K is that it is temperature stabilized, making it applicable to both hot and cold environments.

Besides, such a resistor can also be used in the production of TV sets, DVD players, computer peripheral equipment, security monitoring equipment, epoxy transformers, etc., where temperature resistance is required. All of the equipment mentioned above are based on electric energy, and thus require CFR-50JR-52-240K which are able to resist the required temperature range.

Working Principle

The working principle of the CFR-50JR-52-240K lies in two elements: resistance and reactance. The resistance determines the degree to which a current flows through the resistor. The reactance in the resistor is responsible for the frequency dependency of a resistor\'s resistance value. The reactance in this kind of resistor is inversely proportional to the frequency while its resistance being constant. Thus when the frequency changes, the resistance also changes accordingly.

This type of resistor gains its resistivity from the profile of the winding pattern in its core, usually in spiral or semicircular shape, which produces an inductance effect. Depending on the size of the core, the inductance can vary from 0.1mH to 20mH or more. The reactance of this kind of resistor is a function of the frequency and the inductance, which affects the total impedance of the circuit.

In addition, this type of resistor usually contains soft metal annealed core that makes them exceptionally resistant to vibration and external impacts. Their terminals are firmly attached to the circuit board and soldered into place, providing a secure connection. This type of resistor also contains flame resistant epoxy materials which provide additional protection against mechanical damage.

In summary, the CFR-50JR-52-240K through hole resistor is a popular component used in home electronics and consumer products. The application field and working principle of this resistor are closely related to its resistance and reactance elements. It has a wide range of uses due to its temperature stability and reactance based on the inductance of the winding pattern, as well as its soft metal annealed core and flame-resistant epoxy materials.
