Product Description: The 82k Ohm 1/4 Watt Resistor is a high-quality passive component essential for controlling current flow in electronic circuits. These carbon film resistors are designed with a 5% tolerance, ensuring reliable performance for general-purpose applications. With a standard 0.25W power rating, they are ideal for pull-up/pull-down configurations, signal conditioning, and timing circuits in both hobbyist and industrial projects.

Key Features

  • Stable Performance: Carbon film construction provides excellent long-term stability and low noise.

  • Standard Through-Hole Design: Features axial leads for easy mounting on breadboards or permanent soldering on PCBs.

  • Colour Coded Identification: 4-band colour code (Grey, Red, Orange, Gold) for quick manual sorting.

  • Flame Retardant Coating: Built with safety-standard coating to prevent combustion during minor overloads.

  • Compact Footprint: Small axial size (approx. 2.3mm x 6mm) allows for high-density circuit placement.

Technical Details

  • Operating Voltage: Maximum working voltage of 250V for standard electronic environments.

  • Overload Voltage: Can withstand peak voltages up to 500V for short durations.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, maintaining resistance accuracy across heat cycles.

  • Noise Level: Low current-noise levels suitable for high-impedance logic circuits.

  • Moisture Resistance: Protective lacquer coating prevents oxidation of the carbon element in humid conditions.

  • Lead Material: Solder-plated copper leads for excellent wetting and strong mechanical bonds.

  • Resistance Range Stability: Designed to operate reliably within a temperature range of -55°C to +155°C.

  • Mounting Compatibility: Fits standard 0.1" (2.54mm) pitch breadboards and prototyping boards.

  • Applications: Widely used as a pull-up resistor for microcontroller pins or as a voltage divider component.

  • Colour Code Breakdown: Grey (8), Red (2), Orange (x1000 multiplier), Gold (±5% tolerance).

  • Load Life: Maintains resistance within ±3% after 1,000 hours of operation at rated power.

  • Shelf Life: Indefinite storage life when kept in non-corrosive, dry environments.

  • Safety Standard: Designed to fail open-circuit during extreme overloads rather than shorting.

  • Precision: High-quality manufacturing ensures values stay within the 5% window under normal load.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: When using a 9V battery, an 82k Ohm resistor can be used as a high-impedance pull-up to keep input pins high while drawing only ~0.11mA, maximising battery life.

  • 18650 Monitoring: Use two 82k Ohm resistors in series to create a simple voltage divider for measuring high-voltage battery levels with a 5V microcontroller ADC.

  • IC Protection: Ideal for limiting current to the gates of MOSFETs or the base of NPN transistors to prevent unintended switching from stray noise.

  • Related Products: We recommend pairing these with our Half-Size Breadboards and Assorted Jumper Wires for seamless prototyping.

Package Includes

  • 5 x 82k Ohm 1/4 Watt Carbon Film Resistors.
