Trimmer Potentiometers

Trimmer potentiometers, also known as preset potentiometers or trimmers, are small single-turn or multi-turn variable resistors that are mainly used to adjust, or trim, the resistance of a circuit. Trimmer potentiometers are usually mounted on printed circuit boards (PCBs) as their range of travel is relatively short compared to other potentiometers. The 3386P-1-224LF trimmer potentiometer is one of many variations of trimmer potentiometers available today.

The 3386P-1-224LF trimmer potentiometer is a multi-turn trimmer with a resistance of 224Ω ±20%. This potentiometer is designed to fit in a 0.18″ (4.6mm) diameter hole with a conical and linear taper type. The resistance can be adjusted using a slotted, threaded shaft and locking nut combination. The 3386P-1-224LF trimmer potentiometer is designed to operate at temperatures between -55°C and +125°C. It also features a solderable wire-wrap termination type for ease of connection to the PCB.

Application Field

The 3386P-1-224LF trimmer potentiometer is a versatile component, with a wide range of applications with thin-film technology, such as audio and video equipment, automotive electronics, instrumentation, test and measurement, and medical electronics. It can be easily configured in series, parallel, or mixed type connections.

This trimmer potentiometer is most commonly used in audio circuits, such as audio filters and amplifiers, for adjusting the frequency response or gain of a circuit. It is also used in a variety of automotive applications, such as automobiles, airplanes, and motorcycles, for adjusting motor control circuits, air conditioning systems, and electronic fuel injection (EFI) systems.

Other common applications of the 3386P-1-224LF trimmer potentiometer include electronic test and measurement instruments, such as multimeters and oscilloscopes, for adjusting the resistance in a variety of test and measurement circuits. Furthermore, this trimmer potentiometer is also used in medical electronics for adjusting current and voltage levels in medical equipment.

Working Principle

The 3386P-1-224LF trimmer potentiometer works on the principle of varying resistance. When the shaft of the trimmer potentiometer is turned, the resistance of the circuit changes, altering the voltage and current levels in the connected circuit. This change in voltage and current levels can be used to control and vary the frequency response or gain of the circuit.

The 3386P-1-224LF trimmer potentiometer features a tapered resistor element and a linear taper type, which gives it a very smooth, linear behavior over a wide range of resistances. This is ideal for applications such as audio amplifiers and EFI systems, where precise and precise control of voltage and current levels is required.

Conclusion

The 3386P-1-224LF trimmer potentiometer is a versatile and precise component that can be used in a variety of applications. Its adjustable resistance and linear taper allows it to be used in critical circuits such as audio, automotive, and medical electronics for controlling voltage and current levels.
