Product Description: The 50K Preset Variable Resistor is a compact, board-mountable solution for semi-permanent circuit adjustments. Known as a "trimpot," this RM065 package is designed to be tuned during the calibration phase of a project using a precision screwdriver. It is an essential component for engineers and hobbyists who need to "set and forget" specific resistance values or voltage levels in their designs.

Key Features

  • Miniature RM065 Package: Small form factor optimised for high-density PCB layouts.

  • Top Adjustment Slot: Easily accessible for tuning with standard precision screwdrivers.

  • Standard 3-Pin Interface: Compatible with breadboards and stripboards for fast prototyping.

  • Linear Taper: Provides a constant rate of resistance change for predictable calibration.

  • Pack of 2: Ensures you have a spare or can use them for stereo/dual-channel balancing.

Technical Details

  • Resistive Element: Constructed with a durable carbon film for reliable electrical contact.

  • Operating Voltage: Rated for a maximum of 50V DC across the outer terminals.

  • Rotational Angle: Total mechanical travel is approximately 270° (±20°).

  • Rotational Torque: Smooth tuning with a torque range of 20 to 450 gf.cm.

  • Temperature Stability: Operates reliably in environments from -10°C to +70°C.

  • Insulation Resistance: Minimum of 100MΩ at 100V AC to prevent circuit leakage.

  • Load Life: Maintains stable resistance within 5% change after 3 hours of continuous load.

  • Rotational Life: Designed for an adjustment life of up to 100 cycles, ideal for calibration.

  • Residual Resistance: Low residual resistance (typically <30 ohms) at either end of the turn.

  • Material: Features a phenolic base or resin mould for enhanced mechanical strength.

  • Humidity Resistance: Tested for stability even after 350 hours at 40°C and 90% relative humidity.

  • Lead Diameter: Standard 0.5mm leads for secure soldering and stability.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: This 50K preset is perfect for setting the threshold of a 555 Timer circuit. Adjust the trimpot to change the timing intervals or LED blinking frequency.

  • 18650 Power Projects: In battery-operated devices using 18650 cells, use this trimpot as a reference voltage divider to calibrate the analogue-to-digital converter (ADC) readings on an Arduino.

  • IC Integration: Ideal for setting the contrast on a 16x2 LCD screen or adjusting the bias on a Transistor/Op-Amp stage.

  • Capacitor Suggestion: Pair this with a 100nF ceramic capacitor between the wiper and ground to smooth out the output signal and reduce electrical noise.

  • Related Products: We recommend keeping a Precision Screwdriver Set and Multimeter handy for accurate calibration of your trimpots.

Package Includes

  • 2 x 50K Preset Variable Resistor Potentiometers (RM065).
