Introduction of Through Hole Resistors

A resistor is an electrical component with a specific, constant resistance. The resistance generally limits the amount of current that can flow in a circuit, making it an important element in electrical and electronic systems. The resistors used in electrical and electronic systems usually contain two terminals for connections and a resistive element. Resistors can be divided into two types according to how they are used in systems: through hole resistors and surface mount resistors.

Through Hole Resistors

Through hole resistors, also known as conventional resistors, are smaller and less expensive, but they take up more space due to their physical size. Through hole resistors are placed on pcbs and connected by soldering joints, making them more difficult to install than surface mount resistors. Through hole resistors can be used in both digital and analog circuits, such as power circuits and signal circuits.

RNC55K4020FSBSL Application Field and Working Principle

RNC55K4020FSBSL is a leaded resistor with 5% tolerance, 5K Ohm resistance, and 40W power dissipation. The RNC55K4020FSBSL is a through hole resistor which can be used for overcurrent, limiting, snubbing, timing, voltage drooping circuits, and other applications. As a through hole resistor, the RNC55K4020FSBSL has two leaded tinned copper wires that make solder joints with the circuit board. This allows it to be easily mounted to the board, and it also ensures secure connection to the circuit board. When voltage is applied across the terminals, the RNC55K4020FSBSL will limit the flow of current by dissipating the energy in the form of heat. The amount of energy dissipated is determined by the resistors resistance. The resistor will also act as a voltage divider. Its resistance allows it to split voltage into two parts, one part being higher and the other part being lower, depending on the value and the size of the resistor.

Conclusion

RNC55K4020FSBSL is a through hole resistor that can be used for many applications. It is easy to mount the resistors on the circuit board by soldering tinned copper wires. The resistor can limit the current flow and acts like a voltage divider to split the voltage into two parts. Through hole resistors are a cost-effective and reliable solution for many electrical and electronic system designs.
