Through Hole Resistors, such as the RNC50J4870FSRSL, are essential components in virtually all types of electronic circuits, from power supplies to consumer electronics. They are used to create a voltage across inductors and capacitors, as well as providing impedance in oscillators, filters, and other circuits. So, what are through hole resistors and what role do they play? This article provides an overview of the role of through hole resistors and how the RNC50J4870FSRSL works to make them an indispensable part of many circuits.

Through hole resistors are made up of a resistor element and two metal prongs that stick out from it. The two prongs fit in a larger hole in the circuit board, allowing the resistor to be physically connected to the board. The resistor element comes in various shapes and sizes, but typically is made from a conductive material such as copper or silver and encased in a ceramic or plastic casing. By varying the resistive value of the resistor, the conductance of the resistor can be adjusted, allowing for precise control of circuit behavior.

The most common type of through hole resistor is the RPC50J4870FSRSL, which has a voltage rating of 50 volts, a power rating of 1/2 watt and a resistive value of 20 ohms. This type of resistor is typically used in low voltage power supplies, series circuits, and digital signal processing (DSP) circuits. Other common types of through hole resistors include the RPC47F4550SLSR, which is a lower power version of the RPC50J4870FSRSL, and the RPC55J4870FSRSL, which is a higher power version of the RPC50J4870FSRSL.

The working principle of the through hole resistor is relatively straightforward. When a voltage is applied across the resistor, it’s resistive value will cause the current to drop. This drop in current limits the amount of power passing through the resistor and is what allows precise control of the circuit behavior. The RPC50J4870FSRSL is a type of fixed resistor, meaning its resistive value remains constant regardless of the voltage applied, making it ideal for low voltage power supplies and other circuits where precise control over the current is needed. When used in series circuits, multiple resistors can be used in parallel to increase the overall resistance and thus the current drop.

The applications of through hole resistors are wide-ranging, from low voltage power supplies to complex digital systems. They’re also used in high frequency oscillators, filters, and attenuators, allowing engineers to precisely control these components of a circuit. The use of through hole resistors in these types of circuits increases the cost of the circuit slightly, but in most cases, this cost is outweighed by the increased reliability and improved performance gained by using them.

In conclusion, through hole resistors, such as the RNC50J4870FSRSL, are essential components in many types of electronic circuits and devices. They provide precise control over the current that passes through them, allowing engineers to create reliable and efficient circuits, while reducing design and build time.
