Through Hole ResistorsThrough-hole resistors are a type of resistor that is mounted on a printed circuit board (PCB) by inserting the leads of the resistor through holes in the PCB and soldering them in place. Through-hole resistors are commonly used in electronics, as they provide a stable and reliable way to add resistance to a circuit. Through-hole resistors come in a variety of sizes and shapes, with the most common type being the cylindrical shape with axial leads. Through-hole resistors are typically marked with colored bands that indicate their resistance value and tolerance. They are often used in applications where the resistor needs to be easily replaceable or where the circuit is expected to undergo changes over time.
