Through Hole Resistors

Introduction

Through Hole Resistors (RN55E78R7DBSL) are resistors enclosed in a ceramic or epoxy body with two external metal leads through which current flows. They are used in various electrical and electronic circuits for the purpose of providing a stable voltage or current to other components in the circuit.

Application Field

Through Hole Resistors are commonly used in various applications where a stable voltage or current needs to be supplied, such as in voltage dividers, current-limiting circuits, impedance matching networks, and damping circuits.Through Hole Resistors are often used in mission-critical applications such as in aerospace and military applications, as they are known to offer reliable and consistent performance.Further, Through Hole Resistors are widely used in automotive and medical electronics, as these are highly rugged devices that can withstand extreme temperatures and harsh environment conditions.

Working Principle

As the name suggests, Through Hole Resistors consist of two metal leads embedded within a ceramic body or an epoxy body. The two external leads are connected to a conducting material, usually graphite.When current flows through the resistor, the graphite material inside the resistor restricts the flow of electrons and in turn, resistance is provided by the resistor. This resistance is then utilized to create a stable voltage or current by controlling the amount of current that flows in the circuit.Through Hole Resistors are known to be reliable and consistent in their performance, as the same conductive material is used to make each resistor. This ensures that the amount of resistance offered is completely consistent throughout different resistors of the same type.

Conclusion

Through Hole Resistors (RN55E78R7DBSL) are resistive devices that consist of two metal leads embedded within a ceramic or epoxy body. They are widely used in various applications where a stable voltage or current needs to be supplied, such as in voltage dividers, current-limiting circuits, impedance matching networks, and damping circuits. The working principle of Through Hole Resistors is based on the resistance offered by the graphite material inside the resistor restricting the flow of electrons. Through Hole Resistors are highly reliable and consistent in their performance, as the same conductive material is used to make each resistor.
