Product Description The 2K Ohm RM065 Trimpot Trimmer Potentiometer is a compact, single-turn variable resistor designed for PCB mounting. Also known as a trimpot or preset, it is specifically engineered for circuit calibration and fine-tuning. This 2K ohm version is frequently used in voltage divider circuits and for setting reference points in analogue designs. Its miniature open-frame design makes it an essential component for high-density electronic prototypes.

Key Features

  • Precise Calibration: Ideal for initial circuit tuning and long-term stable performance.

  • PCB Friendly: Standard 3-pin configuration with a 5mm pitch for easy soldering.

  • Compact RM065 Package: Small footprint (approx. 7mm x 6.5mm) for space-constrained boards.

  • Simple Adjustment: Top-access screwdriver slot allows for quick, hassle-free resistance changes.

  • Reliable Performance: Features a carbon film resistive element for smooth linear tapering.

Technical Details

  • Resistive Element: Carbon film material ensuring a standard linear (B) taper.

  • Voltage Rating: Supports a maximum operating voltage of 50V DC.

  • Rotational Angle: Total mechanical rotation is approximately 210° to 270°.

  • Torque Range: Smooth rotational torque between 20 to 200 gf.cm for fine control.

  • Insulation Resistance: Rated at more than 100MΩ at 100V DC for signal integrity.

  • Operating Temperature: Reliable performance across -10°C to +70°C.

  • Residual Resistance: Low residual resistance, typically less than 5% of the total value.

  • Mechanical Life: Designed for calibration cycles, with a rotational life of around 20 to 100 cycles.

  • Humidity Stability: Tested to withstand high humidity (90% R.H.) with minimal resistance drift.

  • Marking Code: Labeled with "202" (20 x 10^2) for quick value identification.

  • Mounting Pitch: Standard lead spacing of 5mm (bottom) and 2.5mm (top) for breadboard compatibility.

  • Load Life: Maintains stability within ±5% resistance change after 3 hours of loaded operation.

  • Environmentally Robust: Enclosed cover or open-frame designs offer varied levels of dust protection.

  • Weight: Extremely lightweight, approximately 0.1g per unit.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, use this 2K preset as a variable voltage divider to provide a reference voltage for op-amp comparators or sensor thresholds.

  • 18650 Cell Calibration: Ideal for fine-tuning the low-voltage cutoff in custom 18650 battery protection or monitoring circuits.

  • Resistance and ICs: Perfect for adjusting the contrast of 16x2 LCD modules or setting the output current of an LM317 voltage regulator when paired with the correct fixed resistors.

  • Noise Management: For sensitive analog signals, place a small 10uF electrolytic capacitor near the wiper pin to stabilize the output voltage during adjustment.

  • Related Products: We recommend keeping a RM065 Trimpot Kit on hand for various resistance requirements, or using Jumper Wires for quick breadboard testing.
