Horizontal mounted 10mm carbon trimmer potentiometer with vertical adjust
Application:
• Potentiometer as a Voltage Divider
• Audio Control
• Television
• Transducers
Description:
A trimmer potentiometer is a miniature adjustable electrical component. They're designed for "set and forget" applications to "trim" the value of a resistor in order to provide an exact gain, output voltage, or current. Trimmer potentiometers are mounted directly on circuit boards, set with a small screwdriver and designed for few adjustments during operation.
Several different versions of trimpots are available, using different mounting methods (through hole, smd) and adjusting orientations (top, side) as well as single and multi-turn variations.
Difference between single turn and multi turn potentiometer:
The multi-turn used in applications that require more precise settings.
• Single turn
Single turn trimmers/presets are very common and used where a resolution of one turn is sufficient. They are the most cost effective variable resistors available.
• Multi turn
For higher adjustment resolutions, multi-turn trimpots are used. The amount of turns varies between roughly 5-25, but 5, 12 or 25 turns are quite common. They are often constructed using a worm-gear (rotary track) or leadscrew (linear track) mechanism to achieve the high resolution. Because of their more complex construction and manufacturing, they are more costly than single turn preset resistors. The lead screw packages can have a higher power rating because of their increased surface area.
