TC42X-2-331E

Trimmer Potentiometers

Trimmer potentiometers are small, adjustable variable resistors used to adjust and calibrate electronic systems. The TC42X-2-331E is a high performance trimmer potentiometer with low temperature drift and excellent reliability. It is a single-turn trimmer potentiometer with a standard resistance range of 250Ω to 10KΩ.

Application Field

The TC42X-2-331E is ideal for a variety of applications, such as industrial, automotive, audio, and consumer electronics. It is used in various control systems like frequency synthesizers, electrical amplifiers and position detectors. It is also commonly used for volume control, power supply voltage adjustments, amplifier gain adjustments, and repeating circuit adjustments.

Working Principle

Trimmer potentiometers are mechanical devices that use a core component such as a metal wiper which slides along the resistance element (tungsten, carbon film, etc.) and changes its resistance. The TC42X-2-331E utilizes a single-turn continous sensing track for the adjustment. It also incorporates a low voltage cut-off mechanism, designed to protect the trimmer from accidental over/under voltage conditions.

This trimmer works by resistance variation. The resistance of the wiper decreases as it is moved, which consequently decreases the total resistance of the circuit. To make the adjustment, the user turns the on-board knob which rotates the core component over the resistance element, gradually increasing or decreasing the total resistance of the trimmer. The TC42X-2-331E also comes with a unique clik-lock system for improved accuracy and reliablehold.

Conclusion

The TC42X-2-331E trimmer potentiometer is a high performance component designed for a wide range of applications. The low temperature drift and excellent reliability make this trimmer ideal for important applications which require precise tuning and calibration. Its unique click-lock system and single-turn continous sensing track ensure precise results and an easy-to-use adjustment process.
