Trimmer potentiometers are low-power electrical devices used for adjustment of an electrical circuit. The 3269W-1-100GLF is a trimmer potentiometer from Bourns Inc., a manufacturer of precision electronic components. This potentiometer is well-suited for space-constrained applications and is designed for long-term reliability.

The 3269W-1-100GLF has a leadless package with a snap-in mounting system. The device has a single-turn precision optical trimmer which is operated using an external knob. This feature enables easy adjustment of the device without the need to de-solder the potentiometer from the circuit. The knob generates mechanical movement to the optical shaft of the 3269W-1-100GLF, resulting in changes in resistance values.

The 3269W-1-100GLF has a resistance range of 0.5 Ohms to 100 Kohms. It is available in three different form factors, namely, axial PC, SMD, and right angle mounting. The potentiometer has a high dielectric strength, a low temperature coefficient, and a low noise level. The device also features a wide operating temperature range from -55 to 125°C.

The 3269W-1-100GLF is typically used for control and volume settings, as well as resistance calibration applications. Its low profile and miniature size make it suitable for surface mount, dense packaging, and recent automated assembly methods. The device is typically used in digital servo controls, audio equipment, multi-function meters, and communications equipment.

The working principle of the 3269W-1-100GLF is based on the effects of varying resistance as a function of an external optical shaft. The rotational movement of the optical shaft is translated to an electromechanical movement which results in varying resistance applied to the electrical circuit. As a result, changes to the voltage or current transmitted through the circuit can be controlled by adjusting the resistance value of the 3269W-1-100GLF.

In conclusion, the 3269W-1-100GLF from Bourns Inc. is an example of a trimmer potentiometer which has multiple application fields. The device has a snap-in mounting system, a single-turn precision optical trimmer, and a wide operating temperature range. It is primarily used for control and volume settings, resistance calibration applications, and other audio and communications equipment. The device works on the principle of varying resistance as a function of an external optical shaft.
