Product Description The 3.3k Ohm 1/4 Watt Resistor is a highly versatile passive component essential for electronic prototyping and signal conditioning. These resistors feature a 5% tolerance, ensuring reliable performance in analog and digital timing circuits. With a standard 0.25W power rating, they are an ideal choice for creating voltage dividers, setting transistor bias points, and serving as pull-up/pull-down resistors in low-power electronic designs.

Key Features

  • Optimized for 5V/12V Logic: Frequently used to set the operating point of transistors or as part of RC timing networks.

  • Axial Through-Hole Leads: Standard flexible leads ensure a secure fit in breadboards and easy soldering on PCBs.

  • Color Code Identification: Features the standard 4-band color code (Orange, Orange, Red, Gold) for rapid manual sorting.

  • Stable Carbon Film Construction: Offers high reliability with low electrical noise for clean signal transmission.

  • Flame Retardant Coating: Includes a protective lacquer layer to enhance safety and provide environmental resistance.

Technical Details

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

  • Overload Surge Capacity: Can withstand temporary peak voltages up to 500V for short durations.

  • Dielectric Strength: Provides insulation protection up to 500V AC between the resistive element and external contact.

  • Operating Temperature: Maintains accurate resistance values within a range of -55°C to +155°C.

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, ensuring thermal stability during operation.

  • Lead Material: Solder-plated copper-clad steel leads for high conductivity and excellent solder wetting.

  • Resistance Stability: Engineered to stay within ±3% of the nominal value after 1,000 hours of use at maximum load.

  • Miniature Body Size: Compact axial dimensions (approx. 2.3mm x 6.5mm) for high-density component layouts.

  • Environmental Compliance: Fully RoHS compliant and lead-free for modern manufacturing standards.

  • Low Parasitic Inductance: Suitable for basic RF filtering and high-speed signal conditioning.

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

  • Moisture Resistance: Sealed with multiple epoxy layers to prevent oxidation of the carbon element in humid conditions.

  • Solderability: Meets standard industrial requirements for both manual and wave soldering processes.

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

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 3.3k Ohm resistor is an excellent choice for a pull-up to keep input pins high while drawing only ~2.7mA, extending battery life.

  • 18650 Monitoring: Use two of these resistors in a voltage divider network to monitor 18650 cell levels with high-impedance inputs, keeping parasitic drain low.

  • IC & MOSFET Support: Ideal for limiting current to the base of NPN transistors like the BC547 or as a pull-up for specialised sensor data lines.

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

Package Includes

  • 5 x 3.3k Ohm 1/4 Watt Carbon Film Resistors.
