TWW3JR75E Datasheet/PDFThrough Hole Resistors are resistors that are mounted directly into a circuit board by passing their leads through the board and soldering them on the opposite side of the board. The TWW3JR75E is a through hole resistor, specifically a three watt resistor, which is capable of operating in temperatures up to +125°C and has an anode-cathode spacing of 6.2mm.
Applications
The TWW3JR75E is typically used in many low power amplified audio applications such as pre-amplifiers, mixing boards, and picking up audio source signals. It can also be used in power supplies as a voltage divider or noise filter. Additionally, through hole resistors are also commonly used in automotive electronics, electrical motors, and telecom/electronics systems.
Working Principle
The TWW3JR75E works similarly to other through hole resistors in that its primary function is to conduct current then restrict it. This is accomplished by using resistance within the resistors path which causes a drop in voltage. The higher the resistance of the resistor the lower the current that will be able to travel through it.
The TWW3JR75E specifically is composed of a ceramic body with wire leads through which electricity passes between the anode and cathode. The ceramic body is filled with carbon. As the electricity passes through the carbon, it meets with resistance due to the carbon\'s resistance property thus causing a decrease in the voltage.
The TWW3JR75E also has a positive power rating of three watts meaning that it can handle up to three watts of power through its resistance. This is one of the advantages of the TWW3JR75E over other through hole resistors as it allows for larger currents to pass through the resistor while maintaining its stability.
Conclusion
The TWW3JR75E is a three watt through hole resistor commonly used in a variety of low power amplified audio applications such as pre-amplifiers, mixing boards, and picking up audio source signals. Additionally, through hole resistors are also commonly used in automotive electronics, electrical motors, and telecom/electronics systems. The working principle of the TWW3JR75E is that it utilizes a ceramic body filled with carbon to provide resistance to the current, which in turn will cause a drop in the voltage.
