Through Hole Resistors: RWR78S2552FRB12 Application Field and Working Principle

Through hole resistors, also known as axial lead resistors, are resistors with two leads that are fixed at both ends of a cylindrical resistor body. This type of resistors is the most common form of resistor used in electronics since the 1950s. They are the main type of resistors used in through hole printed circuit board assembly, and the RWR78S2552FRB12 is a typical example. This article explains the application field and working principle of the RWR78S2552FRB12 through hole resistor.

Application Field

The RWR78S2552FRB12 through hole resistor is mainly used in AC/DC circuits. It has an operating temperature range of -60 to +125°C, making it suitable for use in harsh temperature environments. The resistor is designed for a maximum power of 6.25W and has Resistance Value/Tolerance and Temperature Coefficient options available.

Due to its small size and low cost, high-volume applications such as TVs, radio receivers, amplifiers, and computers usually utilize this resistor. These components are also used in a variety of industrial applications, including electric vehicles, solar cells, and wind turbines. Because of its high stability, the RWR78S2552FRB12 resistor can be used in precision measurement and communication systems to maintain accuracy.

Working Principle

A resistor is a passive electrical component that resists current flow. The RWR78S2552FRB12 through hole resistor works in a similar way, producing a voltage drop across its terminals when current flows through it. The voltage drop depends on the resistance value of the resistor, which is marked as an "R" value on the chip body. The more resistance that is present, the more voltage drop is produced.

The working principle of the RWR78S2552FRB12 through hole resistor is also based on the law of Ohm, which states that the current flowing through a conductor is proportional to the voltage applied across it. This means that the resistor\'s ability to resist current flow depends on its R value. When a voltage is applied to the resistor, it will oppose the current and produce a voltage drop across its terminals.

The Resistance Value/Tolerance and Temperature Coefficient options of the RWR78S2552FRB12 through hole resistor can be adjusted to achieve precise voltage drops or accuracy. The Resistance Value/Tolerance is marked as ±(X%), indicating the maximum allowed deviation from the nominal resistance value. The Temperature Coefficient is used to compensate for potential temperature-induced changes in the resistance value and is marked as ±(X)ppm/°C.

Conclusion

The RWR78S2552FRB12 through hole resistor is a common choice for AC/DC circuits, as it offers a reliable and cost-effective solution. Components can be adjusted to meet specific requirements for Resistance Value/Tolerance and Temperature Coefficient, and its high stability and operating temperature range makes it suitable for a large number of applications. With its many features, the RWR78S2552FRB12 is a great choice for a wide range of electronic systems.
