The 202 2K 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 2K ohms and comes in a square body design, which is commonly used in PCB-mounted calibration and adjustment circuits.
This square trimmer is widely used in sensor modules, amplifier tuning, voltage adjustment circuits, and electronics calibration applications. Its small size and stable adjustment mechanism make it ideal for embedded circuits, DIY projects, and general-purpose electronics design.
Key Features:
• Resistance Value: 2K Ohm (marked as 202).
• Adjustable Type: Variable resistor for tuning and calibration.
• Square Body Design: Compact and common for PCB mounting.
• Screw Adjustment: Easy tuning using a small screwdriver.
• Stable Performance: Holds adjustment value reliably during use.
How it Works:
1. Screw Rotation: Turning the adjustment screw changes resistance value.
2. Circuit Tuning: Adjusts voltage/current/signal level in the circuit.
3. Calibration Support: Helps fine-tune circuit output accurately.
4. Stable Setting: Maintains selected resistance 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
