Trimpot (trimmer potentiometer) features include it being a PCB-mountable, high-accuracy, 3-terminal variable resistor used to fine-tune circuits, often adjusted by a screwdriver for precise settings. Other features are its wide range of available resistance values, stable performance under specified voltage, and a resistive element with a sliding wiper to change resistance. Trimpots are ideal for calibration and are available in both single-turn and multi-turn versions for even greater precision.
Features
- Three Terminals: Trimpots have three terminals, providing a total resistance and a variable output via the middle terminal (wiper).
- Preset Adjustments: They are designed for fine-tuning and preset adjustments within a circuit, as opposed to the more accessible knobs of standard potentiometers.
- Screwdriver Adjustment: Most trimpots are designed to be adjusted using a screwdriver, allowing for small, precise changes to the resistance.
- PCB Mountable: They are typically board-mountable, making them suitable for integrating directly onto printed circuit boards (PCBs).
- Wide Range of Resistance Values: Available in various resistance values (e.g., 500R, 5K, 50K), they offer versatility for different electronic applications.
- High Accuracy & Stability: Trimpots are known for their accuracy and are designed for stable performance within their specified voltage and temperature ratings.
- Resistive Element: They contain a resistive element, often made of carbon film or cermet, and a movable wiper that slides across it to change resistance.
- Single-Turn and Multi-Turn: They are available as single-turn and multi-turn potentiometers, with multi-turn versions offering even finer adjustments for greater precision.
- Power Rating: Trimpots have a specific power rating, such as 0.5W, which indicates the maximum power they can handle without damage.
