Trimmer Potentiometers are fine-adjusting devices with three terminals, which have widely been applied in various adjusting system. The 3314J-1-202E is a kind of ceramic trimming potentiometer, which is featured by high precision, stable operation, and strong anti-wetting ability. In this article, the application field and working principle of 3314J-1-202E ceramic trimmer potentiometers will be discussed.

3314J-1-202E ceramic trimmer potentiometers are typically used where very small adjustments must be made on-site. The three terminals of 3314J-1-202E are referred to as a0, a1, and a2. The resistance of the 3314J-1-202E is determined by the position of the wiper arm relative to the two ends of the element, and the resistance can be adjusted by turning the knob.3314J-1-202E is mainly used to adjust resistance, voltage and current in the load circuits. It is widely applied in communications, radio receivers, automatic control engineering, and medical and laboratory instruments. In addition, 3314J-1-202E can also be used to adjust the position of the throttle valve of fuel injection and gasoline engines.

The working principle of 3314J-1-202E is based on the principle of voltage divider. The two ends of the element act as two voltage drops, and the tap is connected to aU terminal for outputting voltage. The voltage output varies with the position of the wiper arm. The ratio of the two resistances to each other determines the output voltage. If the wiper arm is moved from one end to the other end of the element, the output voltage will vary from a minimum voltage to a maximum voltage.

Finally, it is worth mentioning that 3314J-1-202E is a very reliable and durable, and highly adjustable ceramic trimming potentiometers. It is also not easy to overload it, so it is suitable for use in applications requiring adjustment over a long period of time.
