Product Description: The 330 Ohm 1/4 Watt Resistor is a fundamental electronic component designed to limit current flow and protect delicate parts like LEDs. These resistors are manufactured using carbon film technology, providing ±5% precision for consistent performance in various prototyping and repair tasks. With a standard 0.25W power rating, they are the most common choice for breadboard experiments, microcontroller interfacing, and general-purpose signal conditioning.

Key Features

  • LED Optimised: Perfect resistance value for driving standard Red, Yellow, and Green LEDs from a 5V source.

  • Axial Through-Hole Leads: Long, pliable leads ensure a snug fit in breadboards and easy soldering on PCBs.

  • 4-Band Colour Identification: Features clear markings (Orange, Orange, Brown, Gold) for rapid manual identification.

  • Thermal Stability: Engineered with a protective lacquer coating to maintain accuracy across varying temperatures.

  • Low Noise Design: Carbon film construction ensures low electrical noise, suitable for sensitive analogue circuits.

Technical Details

  • Working Voltage Max: Rated for stable operation up to 250V AC/DC in standard electronic environments.

  • Overload Surge Voltage: Capable of withstanding short-duration pulses up to 500V without failure.

  • Resistive Element: High-quality carbon film deposited on a ceramic rod for long-term reliability.

  • Terminal Strength: Leads are made of solder-plated copper-clad steel for high tensile strength and wetting.

  • Operating Range: Maintains resistance specifications within a temperature range of -55°C to +155°C.

  • Body Dimensions: Standard miniature size (approx. 2.1mm diameter x 6.0mm length) for high-density layouts.

  • Tolerance Grade: Class J (±5%), providing an excellent balance between cost and performance for hobbyist use.

  • Current Limiting: Prevents "thermal runaway" in semiconductors by providing a fixed resistive barrier.

  • Insulation Resistance: The external coating provides a dielectric barrier to prevent accidental shorts against adjacent parts.

  • Frequency Response: Excellent performance in high-frequency signal paths due to low parasitic inductance.

  • Standard Compliance: Built to meet EIA-RS-196A standards for fixed resistors.

  • Storage Stability: Nickel-plated leads and sealed body ensure an indefinite shelf life in dry conditions.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: When using a 9V battery to power an LED, use two 330 Ohm resistors in series (660 Ω) to keep the current safe and prevent the LED from burning out.

  • 18650 Protection: Ideal for use in battery-level indicator circuits for 18650 cells to limit the current drawn by status LEDs.

  • IC & Driver Support: Essential for protecting the digital I/O pins of microcontrollers like Arduino or ESP32 when driving transistors or optocouplers.

  • Related Products: We recommend pairing these with our Half-Size Breadboards and 22 AWG Hook-up Wires for efficient prototyping.

Package Includes
