Product Description 

The 15 Ohm 1/2 Watt Resistor is a robust passive component designed for low-resistance applications requiring enhanced power handling. With a 0.5W power rating, it offers double the heat dissipation of standard 1/4W resistors, making it ideal for current limiting in LED arrays, small motor stabilization, and snubber circuits. These resistors feature a 5% tolerance and stable carbon film construction, providing a reliable resistive barrier for both high-performance prototyping and industrial electronic repair.

Key Features

  • High Power Headroom: The 1/2 Watt rating allows for safer operation in circuits with moderate current flow without thermal failure.

  • Low-Impedance Utility: Optimized for use in power supply filters, audio crossovers, and as a protection element in output stages.

  • Breadboard Compatible: Features thick, tin-plated axial leads that ensure a secure fit in solderless breadboards and easy soldering.

  • Visual Identification: Marked with a clear 4-band color code (Brown, Green, Black, Gold) for instant manual verification.

  • Flame Retardant Coating: Coated with a protective lacquer layer to enhance safety and prevent oxidation in humid conditions.

Technical Details

  • Maximum Working Voltage: Rated for stable continuous operation up to 350V AC/DC.

  • Overload Surge Capacity: Can withstand short-duration peak surges up to 700V without immediate failure.

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

  • Temperature Coefficient: Typically rated at ±450 ppm/°C, ensuring minimal drift during high-load operation.

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

  • Lead Material: Solder-plated copper-clad steel leads for maximum conductivity and mechanical pull-strength.

  • Resistance Stability: Engineered to maintain values within ±3% after 1,000 hours of operation at maximum rated load.

  • Body Construction: Optimized axial size to allow for better air convection and heat dissipation than 1/4W variants.

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

  • Low Parasitic Inductance: Suitable for high-speed switching power supplies and basic signal damping.

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

  • Failure Mode: Designed to fail open-circuit under extreme overcurrent to protect sensitive downstream components.

  • Precision Grade: Standard Class J (±5%) providing a cost-effective solution for power-hungry projects.

  • Solderability: Meets industrial standards for manual soldering and automatic wave soldering processes.

  • Indefinite Shelf Life: Protective coating ensures leads remain viable for long-term storage without degradation.

Prototyping and Engineering Tips from Robogears

  • 9V Battery Use: In 9V battery projects, a 15 Ohm resistor is an excellent choice for driving high-power 1W or 3W LEDs (when used in parallel configurations) to manage current flow safely.

  • 18650 Monitoring: Use this as a Current Shunt. By measuring the voltage drop ($V = I \times R$), you can monitor the discharge current of an 18650 cell using a microcontroller's ADC.

  • IC & Driver Support: Essential for protecting the output stages of motor driver ICs like the L293D or as a series resistor to dampen oscillations in high-speed switching MOSFET gates.

  • Related Products: We recommend pairing these with our Half-Size Breadboards, TIP122 Darlington Transistors, and High Power LEDs.

Package Includes

  • 5 x 15 Ohm 1/2 Watt Carbon Film Resistors.
