Trimmer Potentiometers

Trimmer potentiometers are small three terminal adjustable electronic components used to set or calibrate the operating parameters of devices. 3339P-1-201LF, commonly known as a linear-taper trimmer potentiometer, is a single-turn potentiometer, which is mainly used in a variety of applications for the tuning of electrical systems.

3339P-1-201LF features a small, lightweight construction, making it an ideal choice for tight spaces, its low cost and in-circuit adjustability make it ideally suited for a wide range of applications. The potentiometer is made from anodized aluminum and features a broad operating temperature range of -40°C to 120°C. The potentiometer has a high reliability offering a lifespan of over 2000 cycles.

The 3339P-1-201LF trimmer potentiometer has a variety of application fields. Its superior performance make it an ideal choice for adjusting various electrical devices, such as radio tuners, amplifier equalizers, audio levels, lighting dimmers, as well as flow rate and temperature controllers in industrial equipment. It is also widely used in automotive air conditioners, car audio systems, airbag positioning systems, windscreen wipers and radios.

The working principle of trimmer potentiometer 3339P-1-201LF is quite simple. It has three terminals: the first is connected to the rotating element, the second terminal is connected to the wiper and the third is connected to the outer casing. As the knob moves, the wiper slides across the resistive element, which in turn adjusts the level of resistance. The resistance value at the center terminal is determined by the position of the slider relative to the resistive element.

3339P-1-201LF trimmer potentiometer provides superior precision and repeatability, allowing for precise adjustments of electrical systems and devices. Its superior performance make it a great choice for applications across various industries.
