The 103 10K VR Trimmer Long is a small 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 long-body design, making it easy to adjust using a screwdriver.
This trimmer is widely used in calibration circuits, sensor modules, amplifier tuning, and power supply adjustment applications. Due to its compact size and stable performance, it is ideal for PCB-mounted electronics, embedded systems, and DIY projects where accurate tuning is required.
Key Features:
• Resistance Value: 10K Ohm (marked as 103).
• Adjustable Type: Variable resistor for precise tuning and calibration.
• Long Body Design: Easy adjustment and better handling on PCB layouts.
• PCB Mountable: Suitable for soldering directly onto circuit boards.
• Reliable Performance: Stable resistance adjustment for long-term use.
How it Works:
1. Adjustment Screw: Turning the screw changes the internal resistance.
2. Voltage/Signal Control: Used to adjust circuit voltage or signal level.
3. Calibration Support: Fine-tunes circuit output for accurate performance.
4. Stable Setting: Maintains adjustment during normal operation.
Applications:
• Circuit calibration and tuning
• Voltage and current adjustment circuits
• Sensor module fine adjustment
• Amplifier and audio tuning circuits
• Educational and DIY electronics projects
