Through Hole Resistors are among the most common and versatile components used in electrical circuitry, providing simple and effective control of current and voltage throughout a system. One of the more popular varieties of such resistors is the RWR71S8251FSB12, a resistive device whose application field and working principle are detailed here.
Design
The RWR71S8251FSB12 is a through-hole resistor constructed of a cylindrical shape of metal alloy, usually copper or a copper alloy. The diameter of the metal cylinder is 0.5 inches and the length is 0.25 inches. The resistor is mounted on a terminal block, creating a single piece with one threaded stud and two connected terminals. The RWR71S8251FSB12 has a resistance value of 8.25 ohms, with a tolerance of 5% and a temperature coefficient of approximately 200ppm/ ⁰C. It is rated for up to 550 volts DC.
Application Field
Due to its small size, the RWR71S8251FSB12 is ideal for many different types of applications. It is commonly used in commercial and consumer electronics, where its properties of simplicity, low cost, high power rating and wide availability make it an excellent choice. The resistor is often used in automotive, scientific and industrial applications, such as in control circuits, lighting systems, and power supplies. It is also often used as a variable resistor in Audio Frequency Control (AFC) circuits.
Working Principle
The working principle behind the RWR71S8251FSB12 is the same as that of any resistor. It works by controlling the flow of electric current and converting its energy into heat. When a current passes through the resistor, some of the energy is dissipated as thermal energy. This is due to the inherent resistance of the resistor material, which causes the electrons to slow down and generate heat. The resistor\'s resistance value denotes the amount of the current that will be resisted, and the degree of heat that will be generated. In the case of the RWR71S8251FSB12, 8.25 ohms of resistance will cause the current to flow at a rate of 8.25 amps.
Conclusion
The RWR71S8251FSB12 is an ideal through-hole resistor for many different applications. Its size and shape make it easy to install and its resistance value and over-voltage protection make it reliable. Its simple working principle ensures that it can be used in many different types of circuits and applications. With its modest cost and wide availability, the RWR71S8251FSB12 is a great choice for a wide variety of electronics projects.
