Introduction to Through Hole Resistors
Through Hole Resistors are one of the most common types of electronic components used in circuit board designs. Through Hole Resistors are easy to find and come in a variety of sizes and shapes, making them an attractive choice for designers and engineers. They are typically composed of a resistive material such as carbon-film, ceramic, or metal-oxide film, which is affixed to a thermally conductive, yet electrically insulating substrate board. In order to provide the necessary electrical connections, hole patterns are etched onto the substrate board and pins are inserted into the holes to create the circuit connection.
ERX-3SJR51A Application Field and Working Principle
The ERX-3SJR51A Through Hole Resistor is one of the most commonly used Through Hole Resistors for circuit board designs. It is an economical resistor based on a thin oxide metal film technology which has low noise and excellent long-term stability. This is achieved by utilizing an alloy composition consisting of aluminum alloy electrodes, high temperature solder and silver epoxy epoxy encapsulation. This combination provides superior heat dissipation and durability for superior long-term performance.
The ERX-3SJR51A through hole resistor is a fixed resistor which is available in a range of resistance values from 10 ohms up to 1 MOhm. Its resistance depends on the length and thickness of the metal alloy film layer which is cut onto the substrate board material. The ERX-3SJR51A utilizes an epoxy encapsulation for maximum heat dissipation and protection against dust and corrosion. The resistors are usually printed on standard double sided PCB boards, however, they can also be surface mounted. The ERX-3SJR51A Through Hole Resistor has a wide range of applications including power management, audio systems, automotive electronics, telecom equipment and medical electronics.
The Working Principle of the ERX-3SJR51A Through Hole Resistor is simple yet effective. It consists of two terminals, a positive and a negative, in which an electric current passes when voltage is applied to them. The current then flows through the resistive material which then produces heat. This heat is dissipated into the environment and is used to limit the amount of current that passes through the resistor. The resistive material in the ERX-3SJR51A can be selected to provide the desired resistance needed for the specific application. The resistance value does not change over time due to its superior design which provides excellent long-term stability.
Conclusion
The ERX-3SJR51A Through Hole Resistor is one of the most commonly used components for circuit board designs. It is an economical, yet reliable, resistor ideal for a variety of purposes. Its application field is wide due to its versatility and its superior heat dissipation and long-term stability. The Working Principle of the ERX-3SJR51A Through Hole Resistor is based on the use of an all alloy composition to provide excellent electrical and thermal performance. This resistor is highly popular among hobbyists and engineers alike due to its wide range of uses and its reliable performance.
