If you're into electronics, DIY projects, or industrial repairs, these aluminum shell resistors are super handy. Each one is rated for 25 watts with a resistance of 100 ohms and a ±5% tolerance. They're made with a wirewound element inside a sturdy gold aluminum shell that acts as a heat sink. Dimensions are about 27mm long x 15mm wide x 15.5mm high (not including the pins), with pins that are 12.1mm long. They're potted for solidity and are temperature, moisture, vibration, and explosion-resistant. Great for use in inverters, LED lighting setups, speaker crossovers, frequency dividers, servo systems, and other industrial control applications. Heads up: they do get hot when in use, so make sure you provide proper heat dissipation and don't touch them while operating. You get 2 resistors in the pack.
