Through Hole Resistors

The RWR80S7870FMRSL is an through hole resistor, which is an essential element in an electronic circuit. This type of resistor is comprised of a metal cylinder with a wire lead connected to the ends, offering resistance between them, regulated by the material used and the thickness of each cylinder. Through Hole Resistors are used to limit current flow, adjust signal levels, divide voltages, and as bias resistors.

Application Field of Through Hole Resistors

Through Hole Resistors are primarily used in the automotive, aerospace, and medical industries, where precision equipment design and component reliability are essential for safety and efficiency. The resistors are helpful for handling big currents and controlling the direction of the current. They are perfect for applications such as power supplies, motor controllers, converters, and medical equipment.

In the medical industry, they are often used in the manufacture of radiation therapy equipment such as linear accelerators and imaging systems. In the aerospace field, they are popularly used in the manufacture of control systems for aircraft and their navigation and communication systems. Lastly, in the automotive industry, they are an important component in car audio, electronics, and engine control units.

Working Principle of Through Hole Resistors

The working principle of through hole resistors is fundamental in electrical engineering. In basic terms, when a potential difference is applied to the two leads, electrons flow towards the grounded lead. The resistance oppsoing this flow of current creates a voltage drop, which is defined as the potential difference between the two leads, divided by the current.

The preferred form of through-hole resistors is the carbon-composition one. Carbon particles, usually graphite, are mixed with a binding agent and pressed into a cylindrical tube.These carbon particles are then heated up which causes the resistance to increase as the carbon particles expand. The more carbon particles, the higher the resistance value.

Through hole resistors also come in metal-film type, where a thin layer of metal is sprayed onto the resistor which offers a more precise resistance than the other type. The thin layer of metal allows the current to pass with less resistance allowing small magnitude signals to be processed.

Conclusion

The RWR80S7870FMRSL is an through hole resistor that is widely used in the automotive, aerospace, and medical industries. The resistor is composed of a metal cylinder with a lead connected to each end, regulated by the material used and the thickness of each cylinder. It is used to limit current flow, adjust signal levels, and divide voltages. The resistor works by applying a potential difference to the two leads, which causes electrons to flow towards the ground and a voltage drop.

The resistance can be different depending on the type of resistor used. Carbon-composition resistors are usually made up of graphite and metal-film ones have a thin layer of metal covering the resistor. Through hole resistors are vital components for precision equipment in the medical, aerospace, and automotive industries.
