Through Hole ResistorsA through hole resistor (RSF12FT105R) is a passive electrical component which provides an electrical resistance in a circuit, as well as storing electrical energy and producing a desired voltage and power rating. Through hole resistors are widely used in commercial and industrial applications.The advantages of using through hole resistors include their lower cost compared to surface mount devices, their larger size for higher current ratings, and their ability to withstand higher thermal temperatures due to their more insulated construction. Additionally, through hole resistors have a more recognizable shape which makes them easier to identify and repair.Function and Working PrincipleThe function of a through hole resistor is to limit the current flow in an electrical circuit by introducing an opposing resistance into the circuit, too low a resistance will cause the current to be too high and potentially damage the circuit components, and too high a resistance will reduce the current to below an acceptable operating level, resulting in improper operation.The working principle of a through hole resistor is relatively simple. It works by allowing a portion of the current to flow through the resistance component in order to dissipate the energy in the form of heat. The resistance of the resistor is determined by the number of ohms it is rated for, which is calculated by measuring the width of the resistor and the distance between its two ends. As the current flows through the resistor, the voltage drop across the resistor is determined by the resistance value divided by the current flow.ApplicationThrough hole resistors have a wide range of applications in various industries. In automotive applications, through hole resistors can be used to adjust and limit the current flowing into the headlights, tail lights, and various sensors. In the medical industry, through hole resistors are used to regulate the current in CT scanners, MRI machines, and other medical imaging equipment. In the communication industry, through hole resistors are used in telephone lines and cellular networks.In terms of industrial applications, through hole resistors are used in factories and various production lines to adjust and regulate the current and current flow in machines and ensure safety for the workers. In addition, these resistors can be found in various consumer electronics such as televisions, DVD players, and video game consoles to adjust the current and voltage levels within the device.ConclusionThrough hole resistors are an essential component in most electrical devices and circuits, as they are able to provide resistance and regulate the current and voltage levels, as well as dissipate the energy in the form of heat. The RSF12FT105R is a type of through hole resistor that is commonly used in a variety of commercial, industrial and consumer applications. It is cost-effective, relatively easy to use, and offers reliable performance in a variety of applications.
