The 103 10K VR Trimmer Square is a compact adjustable variable resistor (trimmer potentiometer) used for fine-tuning voltage, current, or signal levels in electronic circuits. It has a resistance value of 10K ohms and comes in a square body design, making it suitable for PCB-mounted calibration and adjustment applications.
This trimmer is commonly used in sensor modules, voltage adjustment circuits, amplifier tuning, and calibration systems. Its stable adjustment mechanism and small size make it ideal for embedded electronics, DIY projects, and general-purpose circuit designs.
Key Features:
• Resistance Value: 10K Ohm (marked as 103).
• Adjustable Type: Variable resistor for tuning and calibration.
• Square Body Design: Compact and ideal for PCB mounting.
• Screw Adjustment: Easy tuning using a small screwdriver.
• Stable Performance: Holds resistance value reliably during operation.
How it Works:
1. Screw Rotation: Turning the adjustment screw changes resistance.
2. Circuit Tuning: Adjusts voltage/current/signal levels in the circuit.
3. Calibration Support: Fine-tunes output for accurate performance.
4. Stable Setting: Maintains the selected adjustment value during use.
Applications:
• Circuit calibration and tuning
• Sensor module fine adjustment
• Voltage and current adjustment circuits
• Amplifier and audio tuning circuits
• Educational and DIY electronics projects
