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

Product Description The 22 Ohm 1/2 Watt Resistor is a robust, low-impedance passive component designed for high-current signal conditioning and power management. With an upgraded 0.5W power rating, this resistor handles double the thermal load of standard 1/4W variants, making it ideal for current sensing, LED protection in power-heavy arrays, and snubbing in motor circuits. These resistors feature a 5% tolerance and high-stability carbon film construction, ensuring a reliable resistive barrier for protecting sensitive semiconductors in demanding environments.

Key Features

• Enhanced Heat Dissipation: The 0.5W rating allows the component to operate cooler in low-resistance, high-current paths.

• Low-Impedance Precision: Optimized for minimal voltage drops, perfect for shunt applications and circuit stabilization.

• Breadboard Friendly: Features sturdy, tin-plated axial leads designed for a secure fit in solderless breadboards.

• Instant Identification: Clearly marked with a 4-band color code (Red, Red, Black, Gold) for rapid manual verification.

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

Technical Details

• Maximum Working Voltage: Rated for stable operation up to 350V AC/DC in standard circuit environments.

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

• Operating Temperature Range: Reliable performance maintained across a range of -55°C to +155°C.

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