100K Preset Variable Resistor – Potentiometer (Pack of 2 )

Product Description The 100K Ohm RM065 Trimpot Trimmer Potentiometer is a high-resistance variable resistor designed for precision board-level tuning. This "set-and-forget" component is essential for calibrating circuits where a specific resistance value is needed to maintain long-term stability. The 100K value is particularly suited for high-impedance timing, biasing, and signal-conditioning applications in professional and hobbyist electronics.

Key Features

• High-Impedance Calibration: Ideal for fine-tuning circuits with very low current requirements.

• Miniature RM065 Footprint: Compact 6mm circular design saves valuable PCB real estate.

• Top-Facing Adjustment: Features a screwdriver slot for easy access even in crowded enclosures.

• Breadboard Ready: Standard 3-pin configuration with 2.54mm/5mm spacing for rapid prototyping.

• Carbon Film Stability: High-quality resistive track ensures consistent performance over time.

Technical Details

• Resistive Material: High-grade carbon film on a sturdy phenolic base.

• Voltage Handling: Maximum operating voltage of 50V DC across outer pins.

• Rotational Angle: Mechanical rotation of 210° to 270° for a wide tuning window.

• Rotational Torque: Smooth and consistent adjustment feel (20 to 200 gf.cm).

• Insulation Resistance: Rated at >100MΩ at 100V DC to ensure signal purity.
