Introduction

Trimmer Potentiometers are adjustable resistors with three terminals used to vary an electrical signal. This is accomplished by adjusting the resistance in the device by turning an adjustable knob or screw. The 3214X-1-104E is a trimmer potentiometer with a wide array of application fields and working principles.

Application Fields

Trimmer Potentiometers like the 3214X-1-104E are found in many different electronics applications. It is often used for voltage and current adjustment, frequency adjustment, gain feedback control, signal modulation control, and time delay adjustment. Common uses for trimmer potentiometers can be found in amplifiers, radio receivers, transmitters, circuit oscillators, voltage Regulators, switching circuits, logic and signal converters and control circuitry.

Working Principle

The 3214X-1-104E Trimmer Potentiometer operates using a three-terminal variable resistance mechanism. This device consists of a rotational adjustment knob or a screw and three connections; two outer terminals labeled as lower and upper pins, and a center pin. The center pin is connected to a resistive element that connects the two outer terminals, thereby allowing current to flow from one terminal to the other. Turning the knob or screw on the trimmer potentiometer can vary the resistance from 0 to the maximum set value. This permits any specific resistor value to be set within that range. For the 3214X-1-104E, this maximum set value is 25 kilo ohms.

Conclusion

The 3214X-1-104E Trimmer Potentiometer is a versatile and effective device for adjusting voltage, current, frequency, gain feedback control, signal modulation, time delay, and more. It is an excellent component for use in circuitry such as amplifiers, radio transmitters and receivers, frequency oscillators, voltage regulators, switching circuits, signal converters, and many other applications. The device works using a three-terminal variable resistance mechanism and consists of an adjustable knob or screw, two outer terminals, and a center pin. The resistance is able to be adjusted from 0 ohms up to a maximum set value of 25 kilo ohms.
