Trimmer potentiometers are miniature adjustable resistance devices mainly used for adjusting the electrical characteristics of electronic circuits, such as frequency, voltage, current, and gain, with a mechanical control. The 3339H-1-105LF model is an adaptation to the popular 3329H-1-106LF model, which offers superior performance.

The 3339H-1-105LF is a trimmer potentiometer with a maximum of 100 turns and a resistance range of 100 kΩ; its standard resistance tolerance is ±20%. The pot is designed with a sliding shaft (single-turn type) that allows smooth control of the resistance settings. It also includes a locking mount which prevents the shaft from turning when the setting is complete.

The 3339H-1-105LF is characterized by a high level of torque stability and linearity. Its operating temperature ranges between -55°C and +125°C, making it suitable for a wide range of applications in harsh environments. Its accuracy is also quite good, with a temperature coefficient of less than ±50 ppm.

The 3339H-1-105LF is popularly used in radio communication devices, optoelectronics, and audio systems. It is also widely used in automotive applications, such as in steering, airbag, and transmission control systems. In addition, it is used in various industrial applications, including temperature and flow control equipment.

The working principle of the 3339H-1-105LF model is based on the use of a conductive element embedded in a dielectric compound. When power is applied, the element carries an electric current, causing a change in its resistance. This change in resistance is controlled via the sliding shaft, which can be adjusted to match the desired levels.

In summary, the 3339H-1-105LF is an advanced trimmer potentiometer model that is designed for precise adjustment of electrical characteristics in electronic devices. It offers high torque stability, linearity, and accuracy, making it suitable for numerous applications. It is commonly used in radio communication devices, optoelectronics, automotive systems, and industrial equipment.
