Introduction to Trimmer Potentiometers

A trimmer potentiometer is a type of variable resistor that is more often used to make small adjustments in circuit designs. It is usually a panel-mounted device found on equipment, such as stereo systems or other electronic devices. The trimmer is also useful for making adjustments in automobile and appliance electronics. The trimmer potentiometer, often referred to as a trimpot, is basically a potentiometer that is tuned or adjusted with a screwdriver. This adjustable feature offers the convenience of not needing to replace a resistor for each adjustment.

3269X-1-201LF Application Field and Working Principle

The 3269X-1-201LF is a surface-mounting, dual in-line trimmer potentiometer from Bourns, Inc. It has a resistance range of 200ohms and is designed for SMD dimensional tolerances and an operating temperature range of -55℃ to +125℃. This resistor is ideal for applications such as airport lighting, automotive interior lighting, and HVAC/R digital adjustment systems. The main advantage of the 3269X-1-201LF is that it is solderable, and can be mounted on a printed circuit board (PCB).

The 3269X-1-201LF is a three-terminal device consisting of a wiper, a terminal connected to one end of the resistance element, and a terminal connected to the other end. The resistance element is typically made of a film material, but may also be wirewound. The wiper is operated by a screwdriver to adjust the resistance value. When the screwdriver is turned, the wiper will move along the resistance element, increasing or decreasing the resistance value. This operation is known as trimming. Once the desired resistance value is reached, the screwdriver is released, and the wiper will stay in place.

Conclusion

The 3269X-1-201LF is a versatile trimmer potentiometer. It has a wide temperature range and is ideal for applications that require frequent adjustment. It is also solderedable, which makes it an ideal option for SMD PCB designs. In conclusion, the 3269X-1-201LF is an excellent choice for creating adjustable resistances in a variety of settings.
