Through Hole Resistors: ERX-1SJ2R7 Application Field and Working Principle

Through hole resistors, also known as leaded resistors, are components found in electronic circuits. Generally, through hole resistors are manufactured from wire-wound resistive elements and preferably have a thin-film element. They are named so because the lead wires are mounted through two holes in the main body of the resistor.One of the most popular through hole resistors is the ERX-1SJ2R7, which is noted for having a high power rating and a low tolerance of between ±0.01%. It has a rated power of 3 watts and operates between 85°C and 105°C and 20% and 95% relative humidity. This through hole resistor is also durable due to its construction, as it is made with a ceramic coating for insulation and high temperature rating.In terms of its working principle, the ERX-1SJ2R7 uses an insulated metallic resistive element connected to two conductors, known as the leads. These leads are connected to the external circuit and should not be exposed to the environment as they could create an electrical hazard. The resistive element converts the energy from the electric current to thermal energy, producing heat and releasing it into the environment. The higher the electric current passing through the resistor, the more power is dissipated in the resistor and the more heat is generated.The main application field of the ERX-1SJ2R7 is in sensing circuits, whee it measures the voltage in the circuit. It senses the voltage and reduces it to the desired level for input into a device. Alternatively, the through hole resistor can be used in power supplies, regulating the current. The ERX-1SJ2R7 is also used in power switching circuits to control the switching time of the circuit and protect it from inrush currents.Apart from these application, the ERX-1SJ2R7 may also be used in filters, oscillators, clocks and analog switches. It can also be used for voltage divider circuits, which divide the voltage in a circuit while limiting the current. The ERX-1SJ2R7 is also commonly used in others power circuits such as power amplifiers and audio circuits.In conclusion, the ERX-1SJ2R7 is an ideal through hole resistor for use in a variety applications. It has a high power rating and low tolerance, making it suitable for use in circuitry with a high level of precision. Its resistance and thermal properties make it resistant to wear and tear whilst providing efficient performance. Its application field includes sensing circuits, power supplies, power switching circuits, filters, oscillators, voltage dividers, power amplifiers and audio circuits.
