Through Hole Resistors

Through hole resistors are electronic components that allow a specific amount of current to pass through a circuit. The current flow is regulated by the resistance of the component. Through hole resistors are typically small cylindrical rods, usually about 1/2 inch (12.7 millimeters) in length and 1/8 inch (3.175 millimeters) in diameter. The resistors are classified according to their resistance range and other characteristics such as power rating, package type and stability.
