Through Hole Resistors: RSF2WSJR-52-2R Application Field and Working Principle

Through hole resistors are a type of electrical resistors, designed to be mounted in a fixed location by being inserted into their designated hole through a PCB. The RSF2WSJR-52-2R is a type of through hole resistor, designed with a power rating of 2 Watts and a tolerance of 5%.

Applications

This type of through hole resistor is commonly used in high-efficiency power supplies, voltage stabilizers, and buck converters as the leading component in the current path. It is also possible to use this component in reliability applications, such as lighting control and heater systems. This resistor is also used in automotive, telecommunications, and computer equipment, as well as consumer electronics such as television and audio systems.

Working Principle

Through hole resistors consist of two wires with a resistor core in between them. These cores are usually made from carbon, but may also use metal alloy or metal oxide semi-conductors. When current passes through this resistor, it is dissipated through heat, which is why the power ratings are important. As the power rating increases, the heat generated by the resistor increases. As a result, the higher power rating of the RSF2WSJR-52-2R allows it to be used in power supplies with more wattage. The tolerance rating for these resistors is also important, as it indicates the accuracy of the resistance. For this particular resistor, it has a tolerance of 5%, which means that the resistance can be up to 5% higher than the value stated on the resistor. In applications that require precise values, it is important to consider the tolerance rating and select the appropriate resistor.

Conclusion

The RSF2WSJR-52-2R is a through hole resistor with a power rating of 2 Watts and a tolerance of 5%. It is widely used in a range of applications, from power supplies to consumer electronics. It works by dissipating the current passing through the resistor as heat, and its accuracy is dependent on the tolerance rating.
