The Trimmer Potentiometer is a small adjustable resistor used for fine-tuning and calibration in electronic circuits. It is commonly used where infrequent adjustment is required, such as calibration and preset control.
Key Features
Compact preset variable resistor for fine adjustment
Designed for PCB mounting
Adjustable using a screwdriver
Available in various resistance values (e.g., 1kΩ, 10kΩ, 100kΩ)
Ideal for calibration and tuning of electronic circuits
Reliable and stable performance over time
Compatible with Arduino and microcontroller projects
Detailed Description
The Trimmer Potentiometer, also known as a preset or trim pot, is used to make small adjustments to a circuit after assembly. Unlike standard potentiometers meant for frequent user interaction, trimmers are typically adjusted once or occasionally during setup or calibration.
They are widely used in Arduino projects, sensor calibration, amplifier gain adjustment, voltage reference tuning, and power supply regulation circuits. Their compact size makes them ideal for PCB-based designs where space is limited.
Trimmer potentiometers are essential in both educational electronics and professional circuit design, ensuring accurate and stable circuit performance.
