Working Principle

The 3313X-1-203E is an adjustable potentiometer with a linear resistive element. It works by passing a current through the resistive element, which is then divided depending on the position of the wiper. The wiper is a contact point that can move along a resistance track and connect to different points on the resistive element. The resistance between the wiper and the resistance track is the same as the resistance between the two points of the resistive element that it is connected to, so the value of the adjustable pot is determined by the position of the wiper on the track. The total resistance of the device is determined by the total length of the resistive element. The resistance can be adjusted by turning the knob connected to the wiper, which will move the wiper along the track.

Conclusion

The 3313X-1-203E trimmer potentiometer is a highly accurate and rugged component that is used in a variety of applications. It has a wide temperature range and can be used as a voltage divider or to adjust the resistance in circuits. Its working principle is simple and it is easy to adjust the resistance by turning the knob connected to the wiper. This makes it an ideal component for applications where precise adjustments are needed.
