Introduction

Trimmer Potentiometers, sometimes referred to as trim pots, are adjustable resistors used to set or adjust current or voltage levels in an electronic circuit. The 3314Z-GA4-503E is a 3-terminal trimmer potentiometer designed for SMD (Surface Mount Technology) applications. It has a robust construction with two stable plastic locking clips minimising moisture ingress, and a low profile of only 12.70 mm. It includes terminals for both axial leads and printed circuit board mounting.

Application Field

Trimmer Potentiometers have a wide variety of uses, from manual adjustments in the field to critical on-board adjustments. Common applications for the 3314Z-GA4-503E include controlling voltage, such as in controlling speed of motors, or adjusting sound volume in sound systems. This part is also used in automatic system control, such as single-servo drive systems, centralised control systems, and various electronic equipment.

Working Principle

The 3314Z-GA4-503E is a standard 6mm x 6.5mm trimmer potentiometer, and works like a standard potentiometer. It consists of a resistance element along with two electrical contacts (the terminals). By adjusting the knob on top of the device, the slider (wiper) moves along the resistance element adjusting the resistance between the two terminals. The third terminal, or "common", is used for fixed connections, either directly to a voltage source or to a pull-up resistor.The resistance range of the 3314Z-GA4-503E can be changed from 0 - 10K ohms, depending on the resistance element chosen. The resistance element has a high linearity of 15% (i.e. the change in resistance per unit of adjustment is constant over the adjustment range). The device has an operating temperature range of -30°C to +85°C and can be mounted on either axial or printed circuit (pc) board.

Conclusion

The 3314Z-GA4-503E is a trimmer potentiometer designed for SMD applications. It is used to set or adjust voltages levels or currents in electronic circuits and applications range from manual adjustments in the field to critical on-board adjustments. The device operates by adjusting its resistance between two terminals by manually adjusting the knob on the top of the device. The resistance can be changed from 0 to 10K ohms, depending on the resistance element chosen. It has a high linearity of 15% and can be mounted on either axial or printed circuit board.
