Trimmer Potentiometers

A trimmer potentiometer, commonly referred to as a trimpot, is a small-scale adjustable potentiometer device used to calibrate a circuit. It serves a similar purpose to a variable resistor, however it is aimed at more temporary adjustments and requires no physical adjustment. Trimpots are available in various shapes, sizes, accuracies and resistance values, making them suitable for most applications.

3386Y-1-201LF Trimpot

The 3386Y-1-201LF trimpot is a versatile device suited for a wide range of applications, such as signal processing, wireless communications, data acquisition, and factory automation. It is a medium-sized, single-turn, 10 kilohm trimpot from the 3386Y series provides both volume and gain control.

Application Field

The 3386Y-1-201LF trimpot is used where a wide range of electrical resistance values with high accuracy is required. It has a wide range of applications, but is most commonly used for precision calibration and tuning of feedback systems, amplifier circuits, and oscillators. Some other applications of the 3386Y-1-201LF trimpot include actuating reset limits, adjusting timing sequences, and controlling the level of current supplied to inductive loads.

Working Principle

The 3386Y-1-201LF trimpot operates on the same principle as other trimpots. It consists of a variable resistor or rheostat that changes the amount of electrical current passing through it. When the potentiometer is turned, the resistance of the rheostat also changes, shrinking or expanding the current. This variation in resistance is used to modify signal parameters, such as voltage frequency, volume, and gain, in the desired application.

The 3386Y-1-201LF trimpot operates on an analog control principle. It has a metal housing containing three terminals, an external adjusting knob (displayed externally) and an internal, adjustable resistor. The adjusting knob is used to vary the resistance of the rheostat, with a keyway groove providing mechanical detents for precise adjustments. The resistance of the 3386Y-1-201LF trimpot is easily adjusted by turning the knurled knob.

Conclusion

The 3386Y-1-201LF trimpot is a versatile device suited for precise calibration and tuning of feedback systems, amplifier circuits, and oscillators. This trimpot operates on the same principle as other trimpots, consisting of a variable resistor or rheostat that changes the amount of electrical current passing through it. By turning the knob, the resistance of the rheostat can be easily adjusted, enabling users to achieve their desired range and amount of current passing through the device.
