Through Hole Resistors are a type of resistor that is typically designed with long, bendable leads that can be inserted into the drilled holes of a printed circuit board (PCB) and soldered into place, thus securing their position and connecting them within the circuit. They play a crucial role in managing the flow of electricity, transforming electrical energy into heat, and ensuring that the correct amount of current reaches other components without causing damage. They effectively limit the flow of current, divide voltage, and are often used in applications that require high heat dissipation.
These resistors are particularly advantageous for projects or applications that need to withstand high electrical overloads, due to their thermal and electrical stability. They can be found in many electronics and electrical devices such as televisions, radios, and power conversion devices. Several established manufacturers produce through hole resistors, and these include but are not limited to, Yageo Corporation, KOA Corporation, and Panasonic Corporation.
