What are Through Hole Resistors?
A through-hole resistor is a firm resistor that has extended, pliable leads that can be limited to a breadboard, wave-soldered, or hand into the printed circuit board. Also called a leaded resistor, a through-hole resistor is employed to mitigate the flow of electric voltage within a circuit. For general use or for devices requiring high tolerance, through-hole resistors are made of carbon film or metal film, respectively. They are placed (manually or mechanically) into holes on printed circuit boards using long, flexible leads.
Typical applications
We are aware that resistors are frequently used to regulate current flow. In a resistor, electrons collide with ions to reduce the current, slow down the flow of energy, and generate heat. When a resistor is considered to have high resistance, it indicates that at a given voltage, less current flows through it.
Some applications of the resistor are listed below:
- Circuit functions
- Dividing voltage
- Heating
- Frequency and timing
- LEDs and transistor
Types of Resistors
Different sizes and forms are available for resistors. They might be surface-mount or through-hole. A typical static resistor, a collection of resistors, or a unique variable resistor might be what you need.
Through-hole
Resistors have long, flexible leads that may be hand-soldered onto a prototype board or printed circuit board or placed onto a breadboard (PCB). These resistors are often more beneficial for prototyping, breadboarding, or any other situation where you'd prefer not to solder small, tiny 0.6mm-long SMD resistors. These resistors are guaranteed to take up significantly more space than their surface-mount equivalents because of the lengthy leads, which typically need cutting.
Surface-mount
Resistors are tiny, black rectangles with smaller, bright, silver, conductive borders on either side. These resistors are designed to be placed on top of PCBs and soldered onto complementary landing pads. Due to their tiny size, these resistors are often installed by a robot before being heated in an oven to melt solder, which secures them in place.
