Through Hole Resistors
A through hole resistor is a type of resistor that is installed on a circuit board and is staked into a hole in the board. It is used to reduce current flow, adjust signal levels, divide voltages, and even for protection against electrical overloading. An ERX-3SJ2R0 through hole resistor is a standard resistor in the through hole resistor family that is widely used in a variety of electronic applications.
ERX-3SJ2R0 Application Field
ERX-3SJ2R0 through hole resistors are popularly used in applications like frequency dividers, constant temperature control systems, over-voltage circuits, and motor speed control systems. It is a general purpose resistor that is often used in audio-visual equipment, computers, and automotive electrical systems.
In industrial machinery, these resistors are used in motor control circuits. For example, they are used to control the voltage and current in various motors and reduce the risk of the motors getting overloaded. In motor speed control systems, these resistors are used to regulate the speed of the motor, making it possible to safely control motors of all sizes.
ERX-3SJ2R0 Working Principles
The ERX-3SJ2R0 through hole resistors consist of copper and a semiconductor material, known as carbon. The carbon, which is in the form of finely ground powder, is mixed with the copper. The combination forms a resistor core with a resistance rating of either 10, 100, or 1000 ohms.
The inner core of this resistor is supplied with electrical current. When this happens, the electric current passing through the core causes the particles of carbon to become charged. This in turn creates a layer of insulation around the resistor core. The total amount of resistance that the core provides is determined by the density of the carbon particles and the amount of current that is being passed through it.
The resistance of the ERX-3SJ2R0 through hole resistor can be easily adjusted by changing the density of the carbon particles. This allows manufacturers to easily customize the resistor to meet different requirements.
When the resistor is installed, it is staked into a hole in the circuit board. This ensures that the resistor is secure and will not be accidentally damaged even during extended use. It also ensures that the core remains firmly in place so that it can successfully control the flow of current.
Conclusion
The ERX-3SJ2R0 through hole resistor is a widely used component in many electronic applications. This efficient resistor is capable of controlling the flow of electricity in a safe and precise manner. Its easily adjustable resistance characteristics make it ideal for handling power management, voltage and current regulation, and motor speed control.
