Product Description: The 100k Ohm 1/4 Watt Resistor is a high-precision passive component widely used for controlling current and defining voltage levels in electronic circuits. These resistors utilise a carbon film construction to provide reliable stability and low electrical noise. With a standard 0.25W power rating, they are an essential part of any electronics toolkit, perfect for high-impedance applications such as pull-up/pull-down networks and signal biasing.

Key Features

  • High Impedance: Excellent for low-power signal conditioning where minimal current draw is required.

  • Breadboard Compatible: Features standard axial leads that fit perfectly into solderless breadboards.

  • Instant Identification: Easily recognised by the 4-band colour code (Brown, Black, Yellow, Gold).

  • Thermal Protection: Coated with a flame-retardant lacquer to prevent damage during accidental circuit stress.

  • Low Noise Profile: The carbon film design ensures clean signal transmission in sensitive analogue paths.

Technical Details

  • Max Working Voltage: Rated for continuous operation up to 250V AC/DC.

  • Overload Voltage: Capable of handling peak surge voltages up to 500V.

  • Temperature Stability: Maintains resistance accuracy within a range of -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C for consistent performance under heat.

  • Dielectric Strength: Offers high insulation protection up to 500V AC between the element and surroundings.

  • Lead Quality: Solder-plated copper-clad steel leads ensure strong mechanical bonds and excellent wetting.

  • Resistance Drift: Engineered to stay within ±3% of the nominal value after 1,000 hours of continuous load.

  • Compact Dimensions: Miniature axial size (approx. 2.3mm diameter) allows for high-density PCB layouts.

  • RoHS Compliant: Manufactured using lead-free and environmentally friendly processes.

  • High Frequency Capability: Low parasitic inductance makes it suitable for basic filtering and timing.

  • Standard Tolerance: Class J (±5%) offers a perfect balance of accuracy and cost for general-purpose use.

  • Moisture Resistance: Sealed with protective layers to prevent oxidation in humid environments.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery applications, a 100k Ohm resistor draws only 90µA, making it the ultimate choice for pull-up pins to maximise battery life.

  • 18650 Monitoring: Use two 100k resistors in series to build a voltage divider for monitoring 18650 cell levels with a microcontroller ADC.

  • IC & MOSFET Support: Ideal for discharging the gate of a Power MOSFET to ensure it turns off completely and stays off.

  • Related Products: We recommend pairing these with our Half-Size Breadboards and 22 AWG Jumper Wires.

Package Includes

  • 5 x 100k Ohm 1/4 Watt Carbon Film Resistors.
