Trimmer Potentiometers

3386R-1-500LF potentiometers are general purpose, top or side-adjustable, single-turn, miniature trimmer potentiometers. They provide simple solutions for adjustment problems where it is necessary to change resistance levels to obtain the best performance from various electronic circuits.

Application Field

These precision trimmer potentiometers can be used as adjusters ofr various applications such as radios, TVs, automotive and medical devices, as well as printers and other computer peripherals. The size and shape of the 3386R-1-500LF trimmers allow for easy use in narrow or crowded compartments. It also has a wide range of values, higher power dissipation, higher current handling capability and wide temperature range, making it suitable for even the most demanding applications.

Working Principle

The working principle of trimmer potentiometers is based on the amount of resistance which is set by turning the adjustment screw of the trimmer. When the adjustment screw is turned one way, an increase in resistance is detected; when turned back the other way, a decrease in resistance is detected. The resistance is adjusted until the desired change is reached and the corresponding circuit parameters are adjusted accordingly.

In the case of the 3386R-1-500LF potentiometers, the adjustment screw is mounted at the top or side of the potentiometer and is easily accessible. The shaft of the potentiometer is protected by a sealed, over-moulded spindle rotating system. This spindle is designed to reduce the effects of dust, dirt, and other contaminants that can interfere with the correct operation of the potentiometer.

The 3386R-1-500LF potentionmeters is available in various case configurations and has a variety of contact options to suit any application. These options include single contact, double contact, open or sealed ...

In addition, the 3386R-1-500LF potentiometers also provides a "snap-in" design that allows for easy installation and is compatible with many other mounting styles. This ease of installation greatly simplifies the overall installation process.

Conclusion

The 3386R-1-500LF trimmer potentiometers are designed for general purpose applications that require precision adjustment. They allow for a wide range of resistance values, as well as higher power dissipation and current handling capabilities, making them suitable for the most demanding requirements. The easily accessible adjustment screw, protected shaft, various case configurations and contact options, and snap-in design offer an easy to install, reliable solution for various circuit adjustments.
