Introduction

Trimmer potentiometers, or trimpots or preset potentiometers, are adjustable resistors with three terminals, of which two are fixed and one adjustable. They are available in a range of resistance values, typically from 10 ohms to 10 megohms. RJR26FW102PQ is one type of trimmer potentiometers, it\'s application field and working principle will be discussed below.

Application Field

The RJR26FW102PQ is designed to be used in a broad range of applications including laptop computers, audio systems, automotive instruments, electrical appliances, medical equipment and more. It can be used as a voltage divider, a current limiting device, or an adjustable control element. The low resistance range of the RJR26FW102PQ makes it suitable for second order resistance compensation in audio amplifiers, as well as voltage dividing and motor speed control systems.

Working Principle

The basic principle of the trimmer potentiometer is relatively simple. By applying a voltage across two terminals, an adjustable resistance is created between these two terminals. The third terminal of the trimpot is the adjusting terminal and allows the user to vary the resistance between the two other terminals by turning the shaft of the trimpot. This allows the user to control the voltage and current levels at that specific point in the circuit and as such can be used to achieve adjustable circuit parameters such as frequency or level of amplification.In the case of the RJR26FW102PQ, this specific trimpot allows for up to +/-10% resistance range adjustments. This means that the resistance between the two terminals can be changed by a maximum of 10% in either direction. This gives very specific and accurate control over the voltage and current in the circuit for any given application.

Conclusion

The RJR26FW102PQ is a trimmer potentiometer that is designed for a wide variety of applications such as laptop computers, audio systems, automotive instruments, electrical appliances, medical equipment and more. Its adjustable resistance features provide precise and efficient control of voltage and current levels in the circuit. The low resistance range of RJR26FW102PQ makes it suitable for second order resistance compensation, voltage dividing and motor speed control systems.
