Trimmer Potentiometers, such as the 1-1623850-3, are small components used in electronic circuits to provide a variable resistance value. The resistive element of a trimpot is usually a cermet material - a mix of ceramic and metallic powders and an organic binder. The resistance value of a trimmer pot is adjusted by rotating a small shaft which varies the surface area of the cermet.

Trimmer potentiometers are generally only adjustable when not connected to the circuit. This is because as soon as an electrical current is applied to the circuit, it affects the overall resistance value. This means that the trimmer has to be adjusted before the rest of the circuit can be connected.

The main application field of the 1-1623850-3 trimmer potentiometer is in analog circuits. They are used to adjust the gain of an amplifier or to adjust the frequency of an oscillator. As the resistance can be changed precisely, trimmers can also be used in voltage dividers to provide precise ratios of voltage.

Another application field is digital circuits. In these circuits, trimmer pots can be used to set or adjust thresholds for digital inputs or digital logic systems. This means that a range of voltages can be allowed to trigger digital inputs or outputs.

In addition, trimmer potentiometers are used in power supplies for setting the output voltage, or in motors for controlling the speed. In these applications, potentiometers are adjusted manually or with automated devices depending on the complexity of the device.

Finally, the 1-1623850-3 trimmer potentiometer is also used in test equipment to set or adjust the voltages and sensitivities of various tests. This allows accurate and repeatable tests to be conducted.

The working principle of the 1-1623850-3 trimmer potentiometer is based on the varying of the surface area of the cermet. This variation in the surface area results in a changing resistance. The adjustment is done by rotating the small shaft which moves an adjuster across the cermet surface. This adjuster is made of two small fingers which make contact with different parts of the cermet surface resulting in a different resistance.

The resistance value of the 1-1623850-3 trimmer potentiometer can be adjusted with great accuracy as the adjuster moves in small increments across the cermet. This results in precise adjustments which can be used in a variety of applications.
