Trimmer Potentiometers

A trimmer potentiometer, also known as a trimmer, is an adjustable, three-terminal electrical component that is usually used for adjustment of electrical circuits. It is most commonly used for adjusting the volume level in audio and video equipment, as well as matching circuit impedance and gain settings. Trimmer potentiometers are available in both rotary and slide versions.

The 3296X-1-102 is the most popular type of trimmer pot. It is a miniature, rotary trimming potentiometer commonly used for electronic equipment. It is constructed from two metal plates with a thin plastic film between them. The device has three connections – two for the plates and one for the anchored wiper arm. When the shaft of the device is turned, the wiper arm moves along the surface of the film, changing the resistance between the two plates.

Application Field

The 3296X-1-102 trimmer pot is widely used in many areas such as automotive electronics, consumer electronics, industrial control, instrumentation, IT, telecommunications, medical devices, and instrumentation. It is most commonly used to adjust the volume level in audio and video systems; regulate the current flowing through circuits; adjust the gain of a signal amplifier; match the impedance of components; and adjust the gain of active and passive filters.

Working Principle

The 3296X-1-102 trimmer pot works on the principle of a variable resistor. When the shaft of the device is turned, the wiper arm moves along the surface of the film, changing the resistance between the two plates. The resistance value increases as the wiper arm moves further away from one plate and decreases as it moves closer to the other plate. This change in resistance value affects the output of the circuit, allowing for precise adjustment of the signal level.

The 3296X-1-102 trimmer pots offer a wide range of resistance values, from 1 kilohms to 18 megohms, making them suitable for a wide range of applications. They also feature low power dissipations, short circuit protection, and long-term stability and reliability.

In conclusion, the 3296X-1-102 trimmer pot is a reliable and versatile adjustable electrical component that can be used for a variety of applications. It is a popular choice for many electronics engineers for its low power consumption, short circuit protection, and wide range of resistive values.
