Trimmer potentiometers are small, three-terminal single-turn devices, sometimes known as variometers or adjustors. They feature a central wiper contact arm and two outer stationary terminals. By rotating the contact arm, the electrical resistance between the two outer terminals can be varied, allowing a user to fine-tune a circuit. The RJR26FX201P trimmer potentiometer, in particular, offers versatile performance and excellent long-term reliability.

Application Field

Trimmer potentiometers are mostly used in industrial, automotive and audio-visual equipment. The RJR26FX201P is a precision trimmer designed for such applications, offering superior performance in terms of stability, accuracy, and long-term reliability. It is capable of handling high power values up to 1W, making it ideal for power amplifier or motor control circuits, as well as other applications requiring precise tuning of resistance values. It has a 3-terminal connection and is highly dust and moisture resistant, allowing for reliable operation in harsh environmental conditions. The RJR26FX201P is rated for temperatures up to 135°C, making it suitable for high-temperature conditions.

Working Principle

Trimmer potentiometers work by varying the electrical resistance between two terminals. The stationary terminals are connected to the potentiometer body, while a central wiper arm makes contact with a resistive element, such as a wire wrapped around a core. By rotating the contact arm, the amount of resistance between the two terminals can be adjusted. In the case of the RJR26FX201P, the contact arm is made of gold-plated stainless steel, offering superior performance in terms of durability and noise-free operation.

The resistive element in the RJR26FX201P is composed of a continuous track of precision-machined metal and provides excellent linearity and stability. As with all trimmer potentiometers, the RJR26FX201P is designed to be adjusted manually by hand, with a rotary tool such as a screwdriver. It is thus ideal for applications where frequent or manual tuning of the resistance values is needed.

Conclusion

The RJR26FX201P trimmer potentiometer offers superior performance and long-term reliability in industrial, automotive and audio-visual equipment. It has a 3-terminal connection and is highly dust and moisture resistant, allowing for reliable operation in harsh environmental conditions. The contact arm is made of gold-plated stainless steel and the resistive element is composed of precision-machined metal, offering excellent linearity and stability. The RJR26FX201P is capable of handling high power values up to 1W, making it ideal for power amplifier or motor control circuits, as well as other applications requiring precise tuning of resistance values.
