Trimmer Potentiometers

A trimmer potentiometer (also known as a trimpot or trimmer) is a small component used to adjust the settings in a circuit, usually the bias of an amplifier, for example. It is very similar to the analog potentiometer, but much smaller. The trimmer potentiometer works just like a regular potentiometer, but instead of a manual control knob, it is adjusted with a small screwdriver or other tool. The terminals on a trimpot are usually connected in a three-terminal configuration, with the center tap being the adjustable contact.

3364B-1-204E application field and working principle

The 3364B-1-204E is a small, three-terminal trimmer potentiometer. It is intended for use in adjusting audio, video, and other electronic equipment bias, calibration, and leveling. This trimmer potentiometer is a three-terminal, linear device with the third terminal adjustable by a slotted screwdriver. It is constructed with a conductive plastic element and has a shaft with a single-turn, linear-taper design. It is available in a nominal resistance value of 200 Ω.

The 3364B-1-204E works by using the adjustable end terminal as an output connection. The two end terminals act as input connections. The adjustable terminal is connected to a slider, which is in turn connected to a spiral- or wedge-shaped element. The element is composed of a conductive plastic film that is slotted so that the resistance between the end terminals can be adjusted by sliding the element along the axis of the slider.

When the adjustable terminal is moved, the electrical resistance between the two terminals will increase or decrease, changing the output voltage of the device. This change occurs because the resistance between the two terminals is a function of the distance between them.When the terminal is moved, the resistance between the two terminals increases or decreases.

The 3364B-1-204E is used for adjusting the audio, video, and other electronic equipment bias, calibration, and leveling. It can also be used to adjust frequency response, gain control, and other voltage-controlled functions.

In summary, the 3364B-1-204E is a small trimmer potentiometer that is used for adjusting audio, video, and other electronic equipment bias, calibration, and leveling. It is a three-terminal device with the adjustable terminal connected to a slider which is connected to a conductive plastic element that can be adjusted by sliding it along the axis of the slider. This change in resistance between the two terminals will result in a change in the output voltage of the device.
