Product Description: The 100 Ohm 1/4 Watt Resistor is a fundamental passive component used extensively in electronics for current limiting and signal biasing. These resistors feature a 5% tolerance, ensuring reliable performance for general-purpose applications. With a standard 0.25W power rating, they are perfect for protecting low-power LEDs, serving as base resistors for transistors, or acting as pull-up/pull-down resistors in digital circuits.

Key Features

  • Versatile Resistance: Common value for driving LEDs from 3.3V or 5V logic with moderate brightness.

  • Standard Axial Leads: Pliable through-hole leads allow for easy insertion into breadboards or soldering on PCBs.

  • Quick Identification: Features the 4-band colour code (Brown, Black, Brown, Gold) for easy manual sorting.

  • Carbon Film Technology: Offers high stability and low electrical noise for sensitive analogue paths.

  • Durable Coating: Finished with a protective lacquer to withstand environmental moisture and minor heat.

Technical Details

  • Maximum Working Voltage: Rated for stable operation up to 250V in standard AC/DC circuits.

  • Overload Surge Voltage: Can handle short-duration peak pulses up to 500V without failure.

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

  • Operating Temperature: Maintains accuracy across a wide thermal range of -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C for consistent resistance under varying loads.

  • Lead Material: Solder-plated copper-clad steel leads for high conductivity and strong mechanical joints.

  • Resistance Stability: Engineered to maintain its value within ±3% after 1,000 hours of continuous load.

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

  • Environmental Standards: Fully RoHS-compliant and lead-free for modern electronics assembly.

  • Audio Performance: Low current-noise levels make it suitable for high-impedance audio signal conditioning.

  • High Frequency Capability: Low parasitic inductance allows for efficient use in high-speed signal paths.

  • Class J Precision: ±5% tolerance provides a cost-effective balance for most hobbyist and commercial projects.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 100 Ohm resistor is ideal for powering high-brightness LEDs, providing approximately 70mA of current (ensure the LED can handle this or use two in series).

  • 18650 Monitoring: Use this as a gate resistor for MOSFETs when switching high-current loads from an 18650 battery to prevent high-frequency oscillations.

  • IC Protection: Excellent for protecting the output pins of microcontrollers like Arduino or ESP32 when driving optocouplers or small transistors.

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