k Black VR Original (1k/B102) Code: 78595914

A 1K ohm variable resistor (commonly called a potentiometer or trimpot) is an electronic component that allows you to manually adjust resistance between 0 and 1,000 ohms. It is typically used as a voltage divider or adjustable current regulator in low-power electronic and breadboard circuits.

Key Specifications

• Total Resistance:1,000 Ω (1kΩ)
• Tolerance:Typically ± 10% to ± 20%
• Power Rating:Usually 0.1W to 0.5W
• Maximum Voltage:Generally 50V to 100V DC
• Adjustment Mechanism:Available in rotary (with a knob) or trimmer (adjusted using a small screwdriver) styles.
• Resistance Taper:Linear (B-Type) is the most common for standard variable resistance.

Common Types

• Trimmer Potentiometers (Trimpots):Small, rectangular or circular, PCB-mountable components used for fine-tuning circuits (e.g., Bourns 3296 or RM065 types).
• Rotary Potentiometers:Larger variable resistors featuring a shaft and knob, designed for user-facing applications like volume or brightness controls

Typical Applications

• Sensor Calibration:Fine-tuning analog sensors (like temperature or light sensors) to match microcontroller inputs.
• Voltage Dividers:Adjusting the reference voltage in comparator and op-amp circuits.
• Tuning & Dimming:Low-power audio volume adjustments and basic LED brightness regulation.
