Through Hole Resistors - RWR71S4R75FRBSL

A through-hole resistor (THR) is a type of resistor that is physically mounted in a circuit board by passing one or more terminals through a hole. THRs are often used in automotive, computing, consumer electronics, and test and measurement applications. The THR has been used since the beginning of modern electronics, and continues to be used today due to their ease of compatibility and low cost.

The RWR71S4R75FRBSL is a type of THR with four lead terminations that allow for easy connection to positive and negative voltage sources, as well as other appliances or devices. These resistors are commonly used in industrial, automotive, and consumer applications. Such applications may include, but are not limited to, controlling the speed of a DC motor, measuring current in an electrical circuit, and limiting the current to an LED.

The working principle of a THR is rather simple. The resistor is a piece of conductive material that is placed in a metal housing. Electric current flowing through the metal housing is diverted through the body of the resistor and through the metal lead. This creates resistance to the flow of electricity. The amount of resistance is determined by the size of the resistor.

RWR71S4R75FRBSL resistors are available in a variety of wattages, from 5 watts to 100 watts. The main advantage of using this type of resistor is its ability to handle larger, higher wattage devices, such as motors. These resistors are also capable of withstanding temperatures up to +220° Celsius, making them ideal for high-temperature applications. Furthermore, due to their lead terminations, they are exceptionally easy to install in a circuit board. This increases their compatibility with many different types of circuit boards.

In summary, the RWR71S4R75FRBSL through-hole resistor is a low-cost, reliable component suitable for a wide variety of consumer, automotive, and industrial applications. Its four lead terminations increase its ease of installation in circuit boards, and its ability to handle larger wattage devices makes it an attractive choice for numerous applications.
