Trimmer Potentiometers: 3314J-1-103G Application Field and Working Principle

Trimmer potentiometers are electronic components used for precision adjustment and calibration testing in a variety of different industries. They are designed to regulate output voltage or current, and can be used to adjust virtually any electrical instrument. They are generally used in applications that require the adjustment of precision voltages or currents. One such trimmer potentiometer is the 3314J-1-103G.

The 3314J-1-103G is a low-cost, pre-conditioned, horizontal, 10 turn adjustable trimmer potentiometer suitable for all applications. It has an accuracy of ±20%, and a resistance range of 10 ohms to 500K ohms. It is an ideal choice for voltage/current adjustment and calibration testing in instrumentation projects, and is especially suitable for circuits with high precision demands, such as medical instruments, automotive electronics, and aviation, telecommunication, and other advanced technology applications.

The 3314J-1-103G is encased in an insulated cylinder made of ceramic or plastic, and has a terminal sleeve that connects the trimmer potentiometer to the power source. It is designed to be resistant to dust, moist, and vibration, and can operate consistently in environments with temperatures ranging from -40°C to +85°C. This trimmer potentiometer is also hermetically sealed and is RoHS compliant.

In terms of operation, the 3314J-1-103G is powered by an AC power source or a DC power source, and the internal metal components are designed to create a voltage divider and adjust the output voltage in response to sensed input voltage. This principle is illustrated in the diagram below.

Referring to the diagram above, the three terminals of a trimmer potentiometer are the positive, negative, and adjustment screws, which are used to adjust the voltage outputs. The positive terminal is connected to the input voltage, and the negative terminal is connected to the ground. Turning the adjustment screw clockwise increases the voltage output, while turning it counter-clockwise reduces the voltage output. The output range is determined by the resistance value of the trimmer and is usually between 10 ohms to 500K ohms for the 3314J-1-103G.

In this way, the adjustment screw is used to control the voltage output from the trimmer, so that the electrical signal is delivered to the load at the desired voltage. Since the trimmer is precision-engineered, the amount of adjustment is uniform throughout the range of adjustment. This makes the 3314J-1-103G an excellent choice for precision calibration and voltage/current adjustment.

The 3314J-1-103G is an ideal component for voltage/current adjustment and calibration testing in instrumentation projects. Its low-cost, pre-conditioned design, hermetic sealing, and high temperature operation make it a dependable and reliable trimmer potentiometer suitable for all applications. This makes it a particularly useful choice for medical instruments, automotive electronics, aviation, telecommunication, and other advanced technology applications.
