Through Hole Resistors

Through hole resistors are electrical components operated by a small current or voltage which is used to reduce the current or voltage in other parts of a circuit. These resistors are designed to be inserted directly into a printed circuit board (PCB) rather than traditional surface mount devices. Through hole resistors are an important type of electrical components in many applications, as they can control signals on the PCB and provide protection for the other components against high voltage and high current.
