1309X102

Trimmer Potentiometers

Trimmer Potentiometers, also known as adjustable or variable resistors, are small, precision potentiometers designed to be adjusted to a specific value. They are typically mountable on circuit boards and have a two-turn screw adjustment for accurate setting. The 1309X102 is a slim-line, single-turn potentiometer with a horizontally rotating adjusting screw and a selectable contact terminal type.

Application Field

The 1309X102 trimmer potentiometer is designed primarily for linear adjustment of resistance values between 0.15k and 5k Ohms. It can also be used for tuning of audio equipment, electrical motors, lighting dimmers, signal conditioning control, and as a current limiter or as a variable resistor in an unlimited number of applications. Its wide range of settings makes it an ideal choice for a wide variety of projects.

Working Principle

Trimmer Potentiometers, like other potentiometers, work by applying an electrical current resistance to the variable contacts with the help of a wiper. As the wiper is turned, it directs the current moving through the resistor to increase or decrease the resistance. By adjusting the variable contacts, the resistance can be set to a desired level. This is what makes trimmer potentiometers ideal for precision fine-tuning.

The 1309X102 features a two-turn screw design that works like a helix, allowing users to make fine, precise adjustments to the resistance value. As the screw is turned, it increases or decreases the resistance value with each turn. The two-turn design ensures that the adjustment is accurate and repeatable.

Conclusion

The 1309X102 trimmer potentiometer is a precision, slim-line, single-turn device that is well suited for a variety of applications. It features a two-turn screw adjustment for fine, accurate adjustments of the resistance value to meet specific needs. As a result, it is an ideal choice for many different projects, from tuning audio equipment to controlling signal conditioning.
