Through Hole Resistors: MFR-25JR-52-360R

A through hole resistor is an electronic component that helps to reduce the electrical current in a circuit. The through hole resistor, as the name implies, is a resistor which is installed physically by passing the connecting leads through hole of the printed circuit board, thus it is also referred to as a through hole device. The type of through hole resistor used in this article is called the MFR-25JR-52-360R, where MFR stands for Metal Film Resistor, 25 stands for a tolerance rating of +/- 2%, JR stands for a power rating of up to 0.5 W, 52 stands for temperature coefficients of up to 350ppm/°C, and 360R stands for 360 ohm base resistance.

Application Field

Since MFR-25JR-52-360R resistors are designed with a low power rating, they are most commonly used in low power embedded projects requiring an accurate resistance value and high reliability. These resistors also have a wide range of applications in the field of circuit prototyping, electronics education, SMPS circuits, and other low power analog/digital circuits. As well, these resistors are not limited to using in electronic circuits - they can also be used in the construction of basic mechanical or electromechanical devices to make them operate correctly.

Working Principle

Resistors are generally used to limit the current in a circuit and are typically composed of a special type of ceramic material, commonly known as a resistor. The material used to manufacture the MFR-25JR-52-360R is metal film, which means it is composed of metal that has been evaporated into layers to form a thin film. These layers are electrically insulated from one another. The resistance of the resistor is determined by the size of the film, the thickness of the film, and the material used. In order to increase the accuracy of the resistance value, the metal film is coated with an oxidation-proof coating that prevents it from being affected by any environmental or electrical variables.

The MFR-25JR-52-360R works on the principle of electricity passing through it. When a current is applied to this resistor, the electrical charge passes through the metal film layers and as each layer experiences a drop in voltage due to the resistance, it dissipates some of the energy as heat. This heat energy is dissipated into the surrounding environment and the total amount of current absorbed by the resistor is directly proportional to the resistance value that it is rated for. The MFR-25JR-52-360R has a maximum power rating of 0.5W, meaning it can absorb up to 0.5W of current without experiencing any damage.

Advantages of Using Through Hole Resistor

The main advantage of using a through hole resistor as opposed to a surface mount resistor or other technology is that they are easier to install, as the leads can simply be passed through the holes in the printed circuit board. This also ensures that the resistor is connected to the circuit correctly as the leads cannot be inserted incorrectly. The MFR-25JR-52-360R also supports a higher power rating than many other types of resistors, meaning it can absorb more current without sustaining damage. Finally, the increased precision of the metal film as compared to other technologies ensures highly accurate and reliable resistance values.

Conclusion

The MFR-25JR-52-360R is a popular type of through-hole resistor that is used in many low powered embedded projects. It is designed with a low power rating and is constructed with an oxidation-proof metal film that ensures a highly accurate resistance value. This type of resistor provides a number of advantages over other resistor types, including easier installation and higher power rating. As well, the precision of the metal film ensures reliable and accurate resistance values.
