Through Hole Resistors

Through hole resistors represent one of the most popular and widely employed types of resistors in use today, and their application field and working principle can be attributed to RWR81S6R04FSB12. Usually, through hole resistors have cylindrical bodies with resistive material and are manufactured using different shapes, sizes and materials. The built-in interconnect technology gives the ability to use through hole components in high powered electronic applications.

Operation Principle

The operation principle of a through hole resistor is quite simple. It involves the use of electrical current to transform a resistor element from a conductive material like copper or metal into a resistive material such as nickel or carbon. The resistive material forms a barrier that reduces the current flow when a voltage is applied to the resistor element. To measure the ohms of the resistor, the current flow from the element is measured against a voltage source. This measurement will vary depending on the type and amount of resistive material used in the resistor. As the value of the resistor increases, the voltage necessary to get the desired current is also increased.

Types of Through Hole Resistor

Through hole resistors are available in either fixed or variable types. Fixed resistors are commonly used for high current applications such as light emitting diodes or lamps. Fixed resistors cannot be adjusted or changed.In contrast, variable resistors typically feature an adjustable sliding contact. These adjustable resistors are used mainly for low current applications such as amplifiers or signal conditioning circuits. Variable resistors can be easily adjusted to precisely adjust the value of the resistor. RWR81S6R04FSB12 is a type of through hole resistor which falls into the category of fixed type resistors. It is most commonly used in LED lighting and other high power applications. It is also commonly used in other circuits such as power supplies, temperature monitoring, and voltage regulating circuits.

Other Applications

Apart from LED lighting, through hole resistors are also finding use in other applications such as communications, automotive, industrial automation, and medical systems. In these applications, they are used to control and limit the current flow and determine the voltage used in the circuits. In addition to their use in circuits, through hole resistors are also used in many measurement and calibration systems. These resistors are used as reference resistors to measure the accuracy of digital signal conditioners. The accuracy of these digital signal conditioners can be tested by comparing it with the reference resistance provided by these resistors.

Conclusion

The application field and working principle of through-hole resistors such as RWR81S6R04FSB12 can be attributed to their easy connection, small size, wide range of available values and excellent stability. This makes them an ideal choice for wide range of applications such as LED lighting, automotive, industrial automation, medical systems and other measurement and calibration systems.
