Product Description The 500K Preset Variable Resistor is a high-resistance trimpot designed for fine-tuning electronic circuits where space is limited. This RM065 package is ideal for applications requiring high-impedance adjustments, such as setting thresholds in sensor circuits or timing intervals in long-duration oscillators. As a "preset" component, it is intended to be adjusted during the initial calibration of the device and left in place for consistent performance.

Key Features

  • High Resistance Range: 500K Ohm value allows for very low current flow and high-sensitivity tuning.

  • Miniature Footprint: The RM065 design is perfect for tight PCB layouts where standard potentiometers won't fit.

  • Vertical Orientation: Top-adjust slot allows for easy access even when the board is populated with taller components.

  • Durable Carbon Track: Provides a smooth linear response and maintains its set value over long periods.

  • Value Pack: Comes as a pack of 2, providing excellent value for prototyping or replacement needs.

Technical Details

  • Resistive Element: High-quality carbon film on a phenolic or resin substrate.

  • Maximum Operating Voltage: Rated for up to 50V DC across the outer pins.

  • Mechanical Rotation: Single-turn adjustment with an effective angle of 210° ± 20°.

  • Rotational Torque: Precision-engineered for a smooth feel (20 to 200 gf.cm) during calibration.

  • Temperature Coefficient: Maintains stability within a standard range for carbon-based elements.

  • Insulation Resistance: Greater than 100MΩ at 100V DC to ensure no signal leakage.

  • Climatic Category: Designed to perform reliably between -10°C and +70°C.

  • Lead Strength: Tinned leads are designed to withstand standard soldering temperatures without lifting.

  • End Resistance: Maximum residual resistance is typically less than 5% of the total 500K value.

  • Humidity Stability: Rated for 350 hours of exposure to high humidity with minimal resistance drift.

  • Standard Markings: Clearly labeled with "504" for easy identification in your component drawer.

  • Vibration Resistance: Designed to hold its physical setting even in moderate vibration environments.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: This 500K trimpot is excellent for High-Impedance Sensor Interfaces. Use it to tune the sensitivity of a Piezo vibration sensor or an infrared receiver circuit powered by a 9V battery.

  • 18650 Long-Duration Timers: Because of the high 500K resistance, you can create very long delay timers using a 555 Timer IC while keeping your capacitor size small, which is perfect for low-power 18650 battery projects.

  • IC Calibration: Ideal for the feedback loop of high-gain Op-Amps where you need to adjust the amplification of extremely small signals.

  • Noise Reduction: In high-resistance circuits like this, stray noise is common. Always use a 0.1uF ceramic capacitor near the wiper to bypass any high-frequency interference.

  • Related Products: We suggest using a Precision Ceramic Adjustment Tool (non-conductive) to tune this preset for the most accurate results.

Package Includes
