Through Hole Resistors
Through hole resistors are types of cylindrical resistors that easily mount on printed circuit boards (PCBs) by inserting their leads through holes and then soldering them in place. These electronic components are indispensable in circuit design to regulate or lime current flow. A through hole resistor provides a strong mechanical bond and reliable electrical connections. These resistors have two leads, which are typically made of wire and are bent in a way that allows them to be easily inserted into the PCB and soldered onto the copper traces. The resistive element of the resistor is connected to leads that extend from the body’s each end, facilitating reliable circuit connections.
Functionality and Benefits of Through Hole Resistors:
Through-hole resistors are commonly used in various electronic circuits, offering multiple functions, such as voltage regulation, current limiting, signal conditioning, and impedance matching. They are often preferred in applications where reliability and stability are crucial, as they offer robust mechanical support and are less prone to damage from external factors compared to surface-mount resistors.
