20K Trimpot Potentiometer 3386P

Trimpots, also known as trimmer potentiometers or trim pots, are small-sized potentiometers that provide adjustable resistance. They are a subtype of potentiometers and are commonly used for fine adjustments in electronic circuits. Trimpots are equipped with a small screw or trimmer accessible with a screwdriver or suitable tool to adjust the resistance values.

Trimpots can be classified based on their package types. Here are common trimpot types and package styles:

1. Rectangular: Rectangular trimpots come in a neat rectangular shape and are typically soldered onto the mounting surface.
2. Round: Round trimpots have a cylindrical package and can be easily placed into mounting holes.
3. SMD (Surface Mount Device): SMD trimpots are surface-mountable components and are easily soldered onto printed circuit boards. They are particularly common in densely packed electronic boards due to their small size and low-profile options.
4. Dual-sided: Dual-sided trimpots have adjustable resistance on both sides, allowing their adjustable sections to work in two directions.

Trimpots are widely used in applications where precise resistance adjustments are required. For example, they can be found in tone controls in audio equipment, brightness controls in lighting circuits, signal calibration in precision measurement instruments, and many other electronic devices.
