Through Hole Resistors are an important hardware component in many industries and are used in a variety of applications, such as audio equipment, automotive systems, and process control. The CFR25SJR-52-1K2 is a type of through hole resistor commonly used for resistive applications, and it is classified by its mounting orientation, size, resistance value, temperature coefficient, and power rating. This article will cover the application field and the working principle of the CFR25SJR-52-1K2.

Application Field

The CFR25SJR-52-1K2 type ofthrough hole resistor provides a lower cost when compared to other types of resistors and has many applications in consumer and industrial devices. This resistor is commonly used in home electronics equipment, motor control, audio equipment, automotive systems, and various process control units. In the home electronics industry, the CFR25SJR-52-1K2 is used to adjust volume levels, regulate current, tune frequencies, and as a surge protector. In the motor control industry, the resistor is used to help regulate the current to the motor, the frequency of the motor, and to reduce the current when needed. In the audio industry, the resistor is used to protect speakers from high currents, adjust equalization settings, and improve the overall sound quality. Additionally, in the automotive industry, the resistor is used to reduce radio interference, regulate voltage and current, and as a surge protector for electronic components.

Working Principle

The working principle of the CFR25SJR-52-1K2 is based on the concept of voltage divider. The resistor is connected in series with two other resistors as part of a voltage divider. When a voltage is applied across the circuit, the voltage is divided in proportion to the resistance of the resistor. This allows the voltage to be adjusted or “tapped” from different points in the circuit. Additionally, the resistor acts as a current limiter by reducing the current that can flow through the circuit. The resistor will limit the current that passes through the circuit, allowing for more precise control of the current.

The CFR25SJR-52-1K2 has a temperature coefficient of about ±150ppm/K. This means that the resistance will change by roughly 150ppm per kelvin of temperature change. This ensures that the resistance of the resistor is kept constant over a wide range of temperatures. Additionally, the maximum power rating of the CFR25SJR-52-1K2 is 1/2 watt. This means that when used in a circuit, the power dissipated by the resistor will not exceed 1/2 watt.

Conclusion

The CFR25SJR-52-1K2 is a type of through hole resistor commonly used for resistive applications. This particular resistor is usually used in home electronics, motor control, audio equipment, automotive systems, and various process control units. The working principle of the CFR25SJR-52-1K2 is based on the concept of a voltage divider and it also acts as a current limiter, allowing for precise control of the current that passes through the circuit. The temperature coefficient of the resistor is about ±150ppm/K, and the maximum power the resistor can handle is 1/2 watt.
