Trimmer potentiometers are a type of adjustable electrical resistance device used to precisely control the flow of electric current. The most common types of trimmer potentiometers are the 22AR100LFTR series, which feature a rotary design that allows for fine-tuning of resistance values. They are often used in audio and video equipment, medical devices, and other industrial applications.

The 22AR100LFTR series of trimmer potentiometers is known for its high performance and reliability. The package size is just 0.14 inches, which makes it suitable for a wide range of applications, from automotive to aerospace systems. Due to its small size, the 22AR100LFTR series can be mounted on printed circuit boards with ease. It can also handle high power ratings from 0.1W to 1W, making it suitable for high-current applications.

The 22AR100LFTR series features a versatile three-terminal configuration, which allows it to be connected in either a linear or a rotary manner. For linear applications, it can be used for setting and controlling an adjustable resistance as a variable resistor. For rotary applications, it can be used to control the angle of the rotating shaft or the position of a moveable arm on a switch. It can also be used for control of audio, video, and other frequency-adjustment applications.

The working principle of the 22AR100LFTR series is based on the ohmic resistance of a wire due to its cross-sectional area and length. When electric current passes through a coil of wire wound around a core, the core acts as a resistor, and its resistance value is proportional to the cross-sectional area of the wire and the length of the coil. When the core is rotated, the resistive value changes due to the changing wire length and cross-sectional area; thus, allowing the adjustment of the output voltage.

The 22AR100LFTR trimmer potentiometers are also known for their high accuracy and stability. They can be used in high-precision applications, such as medical, aerospace, and industrial systems. They are also protected from high temperatures and other environmental factors, making them an ideal choice for use in harsh environments.

In summary, the 22AR100LFTR series of trimmer potentiometers are a widely-used, reliable, and highly-accurate device for adjustable resistance applications. It is suited for any application that requires precise control of electric current, such as medical, automotive, aerospace systems, and audio/video equipment. Thanks to its three-terminal configuration, it can be connected in either linear or rotary configurations for fine-tuning of resistance values. Additionally, the 22AR100LFTR series is protected from high temperatures and other environmental factors, making it suitable for use in harsh environments.
