Through Hole Resistors are among the most important components that play a key role in various industrial applications. RC55Y-2K21BI resistors belong to this category, playing a vital part in countless industrial circuit applications. This paper will discuss the working principle of these resistors, their application fields, and the specifications of the RC55Y-2K21BI resistors.

What are Through Hole Resistors and their Working Principle?

Through Hole Resistors, also known as axial resistors, are two-terminal devices that reduce the flow of electrical current through those terminals. The resistor body is made up of a resistive material, and a cylindrical shape with a lead in each end. The resistive material is usually made of carbon, metal, ceramic, and other substances that control the current flow in a circuit. This resistor is usually installed in a PCB (printed circuit board).

The current flow in resistors is inversely proportional to the resistance value, such that a higher resistance value will lead to a lower current flow. This occurs due to the presence of a non-linear impedance resistance in the resistor structure. The control of the current flow takes place at the resistor junctions and depends on the internal resistance of the resistor.
