22 Ohm 0.5W 5% Carbon Film Resistor Axial Through-Hole

Product Overview

The 0.5W Carbon Film Resistor is the robust “big brother” to the standard 1/4W resistor. While it shares the same precision carbon film technology, it is built on a physically larger ceramic core. This increased surface area allows it to dissipate heat more efficiently, ensuring reliability in circuits where standard resistors might overheat or fail.

Why choose 0.5W?

Sometimes, 1/4 Watt just isn’t enough. The 1/2 Watt rating provides a critical safety margin for your designs. It is the preferred choice for power-intensive applications, such as driving high-brightness LEDs, managing current in power supply rails, or working with higher voltage drops where thermal stability is key.
