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.

  • Operating Temperature: Stable operation from -10°C to +70°C.

  • Dielectric Strength: Can withstand 500V AC for 1 minute without internal breakdown.

  • Residual Resistance: Maximum residual resistance is typically under 1% of the total 100K value.

  • Solder Stability: Tinned leads are designed to withstand standard soldering temperatures.

  • Marking Identification: Clearly labelled with "104" (10 x 10^4) for quick identification.

  • Humidity Tolerance: Tested for reliability in high-humidity environments (up to 90% RH).

  • Load Life: Maintains resistance within ±5% after 3 hours of operation at rated power.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Application: Use this 100K preset to tune the Sensitivity of an Infrared (IR) Sensor circuit powered by a 9V battery.

  • 18650 Power Savings: Perfect for setting the high-resistance bias in low-power sleep circuits for 18650-based IoT devices.

  • IC Synergy: The standard value for setting the timing in NE555 long-delay oscillators or adjusting the contrast on large Graphic LCD modules.

  • Capacitor Filtering: Place a 0.1uF ceramic capacitor near the wiper pin to filter out environmental EMI in high-impedance signal paths.

  • Related Products: We recommend using our Precision Ceramic Trimpot Tools for adjustment and Dupont Jumper Wires for breadboard connections.
