Product Description The 3.3 Ohm 1/4 Watt Resistor is a high-performance passive component designed for low-resistance applications such as current sensing and circuit protection. These resistors feature a 5% tolerance, ensuring reliable electrical behavior in standard prototyping and repair projects. With a 0.25W power rating, they provide a stable resistive barrier for low-voltage signal conditioning and filtering in compact electronic designs.

Key Features

  • Low Ohmic Value: Ideal for applications requiring a minimal voltage drop or high-current path stabilization.

  • Axial Lead Format: Standard flexible leads allow for easy insertion into solderless breadboards or permanent soldering.

  • Color Code Identification: Features the standard 4-band marking (Orange, Orange, Golden, Gold) for quick manual sorting.

  • Stable Carbon Film Construction: Offers high reliability with low electrical noise and environmental resistance.

  • Safety Lacquer Coating: Finished with a flame-retardant layer to prevent combustion during minor electrical overloads.

Technical Details

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

  • 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 surroundings.

  • Operating Temperature Range: Reliable performance maintained from -55°C to +155°C.

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

  • Lead Quality: Solder-plated copper-clad steel leads for superior conductivity and strong solder joints.

  • Resistance Drift: Engineered to maintain values within ±3% even after 1,000 hours of continuous load.

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

  • RoHS Compliant: Manufactured using lead-free processes to meet modern environmental safety standards.

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

  • Moisture Protection: Sealed with multiple epoxy layers to prevent oxidation in high-humidity areas.

  • Indefinite Shelf Life: Protective coating ensures the leads and element remain viable for long-term storage.

  • High Thermal Dissipation: Designed to efficiently manage heat generated during low-resistance operations.

  • Precision Class: Classified as Class J (±5%) for cost-effective performance in general-purpose electronics.

  • Standard Packaging: Supplied in a pack of 5 to support multiple prototyping iterations or small-scale production.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: When using a 9V battery, a 3.3 Ohm resistor can be used in series with power transistors to limit inrush current to motors or solenoids.

  • 18650 Monitoring: Use this as a current shunt resistor in series with an 18650 cell to measure discharge current using a microcontroller's ADC pin.

  • IC & Driver Support: Ideal for protecting the output stages of motor drivers or as a snubber component in small switching power supplies.
