Trimmer Potentiometers

A trimmer potentiometer is a type of electronics component that is used to adjust or control a circuit’s resistance level. It is typically used to adjust various electronic characteristics such as frequency, voltage, power, etc. They are also used in audio systems to adjust the levels of sound. Trimmer potentiometers offer a lot of advantages over standard mechanical potentiometers. For example, they are very small and can fit into tighter spaces than regular potentiometers, making them more suitable for use in portable devices and high-density PCBs.

3386U-1-201RLF Application Field

The 3386U-1-201RLF trimmer potentiometer is one of the most popular products in the market. It is widely used in various industries, including consumer electronics, automotive, medical, and industrial applications. It is a 3-terminal, single-turn device and has a wide operating temperature range between -55°C and +125°C. It has a wide resistance range, from 10 ohms to 20k ohms, and a variety of power ratings, from 0.2 W to 0.5 W. Furthermore, the 3386U-1-201RLF trimmer potentiometer is IP65 protected, which makes it resistant to dust and water.

3386U-1-201RLF Working Principle

The 3386U-1-201RLF trimmer potentiometer is constructed with a linear slider assembly with two parallel wiper terminals that rest on the resistive element of the device. The resistance is then adjusted by turning the external control knob. The rotational motion of the knob turns a threaded shaft, which moves the wiper terminals along the resistive element. The resistance value can then be read off the potentiometer when the basic circuit is complete.

Conclusion

The 3386U-1-201RLF trimmer potentiometer is one of the most popular products in the electronics market. It is a small, low-cost, and highly reliable component that is used in a variety of applications. It offers accuracy and precision, as well as a wide resistance range and a variety of power ratings to meet various requirements. Furthermore, it is IP65 protected, which makes it resistant to dust and water.
