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

Product Description 

The 1 Ohm 1/2 Watt Resistor is a precision-engineered passive component designed for low-resistance applications such as current sensing, fusing, and circuit protection. Featuring a 5% tolerance, these resistors provide stable performance in high-current paths. The upgraded 0.5W power rating allows for higher heat dissipation compared to standard 1/4W resistors, making them ideal for power supply filtering, motor driver protection, and DIY electronic prototyping where durability is paramount.

Key Features

• High Power Handling: Rated at 0.5 Watts, providing double the power capacity of standard 1/4W resistors for safer high-current operation.

• Low Ohmic Value: Perfect for use as a shunt resistor to measure current or as a safety fusible element.

• Axial Through-Hole Leads: Features thick, flexible leads optimized for both solderless breadboards and permanent PCB mounting.

• Reliable Identification: Marked with a 4-band color code (Brown, Black, Golden, Gold) for instant value verification.

• Enhanced Thermal Stability: Built with high-grade carbon film to maintain resistance accuracy even under thermal load.

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.

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

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

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

• Moisture Protection: Sealed with multiple layers of flame-retardant lacquer to prevent oxidation in high-humidity areas.

• Failure Mode: Designed to fail open-circuit under extreme overcurrent, acting as a secondary safety fuse for the circuit.

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