Trimmer Potentiometers

A trimmer potentiometer (also known as a trimmer or trimpot) is a variable resistor or resistor-type device used for individual adjustments and fine-tuning. They are physically small, which makes them suitable for applications where space is limited, for example, in portable electronic devices. They are usually meant for adjustment and are not designed for repeated adjustments.

3296Z-1-254LF Application Field and Working Principle

The 3296Z-1-254LF is a trimmer potentiometer with a through-hole vertical mount. With its small footprint (6.35mm x 5.72mm), this trimmer is suitable for applications where space is limited — including cell phones, portable electronics, and other physical electronics. The 3296Z-1-254LF has a linear resistance range of 20Ohm to 254Ohm. This trimmer operates on the principle of varying the ratio between the two resistors in a Wheatstone bridge.

The 3296Z-1-254LF has two separate tracks that span the length of the potentiometer. These two tracks are connected to two separate resistors. As one of the tracks is moved, the resistance between the two tracks varies, thereby allowing for a wide range of resistances. When one of the tracks is moved to the center position, the resistance between the two tracks is equal. When the two tracks are moved in opposite directions, the resistance between them is at its maximum.

The adjustment of the 3296Z-1-254LF is carried out with a small screwdriver. Depending on the desired resistance value, the preferred adjustments can be made by turning the exterior dial to reach the desired value. Depending on the application and use, these trimmers can also be adjusted to very fine values in order to make fine and precise changes to the resistance values.

The 3296Z-1-254LF is used in applications where physical adjustments are necessary and connected to internal components of the device. These trimmers can also be used in a manual setup and can be adjusted for set points, calibration, and more. This type of trimmer is also used to set resistances for filter circuits, tuners, amplifiers, and audio equipment that require precise and specific values of resistance from time-to-time.

The 3296Z-1-254LF is a good trimmer potentiometer for applications that require adjustable resistances and limited space. With its precise and linear response, this trimmer provides good accuracy with its set points and is suitable for a wide range of applications.
