15 Ohm 0.5W Carbon Film Resistor - 5% Tolerance (Pack of 5)

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.
