Introduction to Through Hole Resistors

Through-hole resistors are a type of resistors that have their leads anchored into a printed circuit board by soldering them to metal pads. This type of resistor has been around since the 1950s and is still in use today, because of its reliability and ease of use. Through-hole resistors are typically made up of two different parts: the substrate and the resistive element. The substrate is usually a cylindrical shaped body made of glass, ceramic, or plastic, and it contains the copper foil that carries current through it. The resistive element is then usually a thin sheet of metal such as copper or nickel. As the current runs through the substrate, the thin metal sheet on the resistive element resists the current, creating heat and reducing the current. The advantages of using through-hole resistors include their simple construction, which makes them easy to assemble and repair, and their ability to handle large amounts of power. Also, through-hole resistors are usually more reliable than surface-mounted resistors due to their larger size and they can even be used to create more complex designs such as variable resistors or networks.
