Trimmer Potentiometers

Trimmer Potentiometers, also known as trimpots, trimmers or trimming potentiometers, are a type of manually adjustable potentiometers used to adjust signals within an electronic device. They are produced as three-terminal adjustable resistances with fixed resistors on either side of a potentiometer element.

3292X-1-253LF Application Field and Working Principle

The 3292X-1-253LF is a type of trimmer potentiometer marketed by Bourns, Inc. It is a three-terminal adjustable resistor with a fixed value resistor on either side of a potentiometer element.The 3292X-1-253LF is designed for use in many applications, including audio tone control circuits, on-board volume and balance adjustment for CB radios and similar devices, and tuning of the data selector switches in voltage multipliers. It has a nominal 25 kΩ resistance, and is available in an industry-standard 3/8" square, rugged metal package that makes it well-suited for industrial environments and high-vibration applications. The package has a 0.200" square window to allow for adjustment with a small screwdriver, and is equipped with a knob to facilitate adjustment.The 3292X-1-253LF trimmer potentiometer works through a resistance mechanism; it has a circular wiper rod that is connected to a movable contact on the resistive element. This contact is usually part of a conductive track that runs around the outside of the element. As the wiper is rotated, the contact point moves along the track, altering the resistance. In this way, a trimmer potentiometer can be used to adjust the voltage and / or current in the host device. The 3292X-1-253LF features a high-grade conductive plastic track and has an overall resistance tolerance of ±20%. It has been designed and tested for operation in up to 70°C environments. The potentiometer is RoHS (Restriction of Hazardous Substances) Compliant.

Conclusion

The 3292X-1-253LF Trimmer Potentiometers is a great choice for a wide range of applications, such as audio tone control circuits, on-board volume and balance adjustment for CB radios and other similar devices, and tuning of the data selector switches in voltage multipliers. It is RoHS compliant and can be used in temperatures up to 70°C. It features a high-grade conductive plastic track and has an overall resistance tolerance of ±20%. The trimmer potentiometer is housed in an industry-standard 3/8" square, metal package that makes it well-suited for industrial environments and high-vibration applications, and provides a 0.200" square window for adjustment with a small screwdriver. Overall, it is an excellent choice for precise control and adjustment of signals within electronic devices.
