Trimmer Potentiometers

A trimmer potentiometer, or trim pot, is a type of adjustable resistor used to adjust the operating parameters of an electronic circuit. Trimmer potentiometers are smaller than regular potentiometers and offer a greater range of adjustment, so they are often used to fine-tune the performance of circuits that are difficult to adjust.

1113TR253 Application Field and Working Principle

The 1113TR253 is a trimmer potentiometer designed for use as a voltage divider, used to accurately set voltage levels in precision circuitry and other applications.The 1113TR253 is a three-terminal device with terminals A and B connected to the center point of the resistor track, while the third terminal, C is connected to one end of the resistor track.The 1113TR253 also uses a combination of multi-turn resolution and a wide adjustment range to provide an accurate and repeatable voltage, current, or resistance value in an adjustable trim Potentiometer.

The 1113TR253 has a taper resistance range of 250 to 2200 ohms, making it suitable for a wide range of applications such as voltage or current level monitoring, position sensing, or even temperature sensing.The 1113TR253 also features an integrated flat-top rotor within a solid-state construction, allowing for reliable and consistent operation. This trim pot also comes with a three year limited warranty.

In operation, the 1113TR253 is adjusted using a precision screwdriver or other fine adjustment tool, with an adjustment range of 2.8° between full-scale readings. To ensure proper function, theR253 must be adjusted with respect to its rated electrical performance levels.

Due to its accuracy and repeatability, the 1113TR253 is widely used for applications in precision circuitry, such as medical, military and aerospace devices, and wherever precise trim settings are required.
