A trimmer potentiometer, also known as a trimpot, is a three-terminal device that has a fixed resistance that is adjustable using a screw or wafer. The RJ13B201 is a trimmer potentiometer of the RJ13 Series from Bourns. Specifically, it is a 50-ohm, single-turn, side adjust trimmer potentiometer.

Introduction

Trimmer potentiometers are the most commonly used type of potentiometer, and they are available in a variety of styles and sizes. They are generally used to set and adjust precise values of resistance. Each trimmer potentiometer contains several components including a base, a wiper, and a contact brush, as well as a track and an adjustment screw. The RJ13B201 is a single-turn trimmer, which means that the adjustment knob turns a full 360°.

Application Field

The RJ13B201 trimmer potentiometer is used for applications that require precise adjustment, such as in tuners and sensors. It is also suitable for voltage divider, signal attenuator, and voltage regulator circuits. Additionally, they can be used as digital or analog input rheostats in digital or analog integrated circuits. The RJ13B201 has a rotational life of 25,000 to 50,000 cycles, and an operating temperature range of -55°C to +105°C.

Working Principle

The RJ13B201 trimmer potentiometer is a three-terminal device that has a fixed resistance that is adjustable using a screw or wafer. The three terminals are the base, the wiper and the contact brush. The three terminals are wired in series such that they form a continuous loop. The resistance between the base and the wiper is determined by the position of the wiper along the track. The wiper can move along the track and adjust the resistance of the trimmer potentiometer. Adjustment can also be made by turning the adjustment screw. The adjustment screw adjusts the contact brush of the trimmer. When the contact brush is moved along the track, this will also adjust the resistance.

Conclusion

The RJ13B201 trimmer potentiometer is a 50-ohm, single-turn, side adjust trimmer potentiometer. It can be used for applications that require precise adjustment, such as in tuners and sensors. It has a rotational life of 25,000 to 50,000 cycles, and an operating temperature range of -55°C to +105°C. It is a three-terminal device that has a fixed resistance that is adjustable using a screw or wafer. The resistance between the base and the wiper is determined by the position of the wiper along the track, and adjustment can also be made by turning the adjustment screw.
