The L100J25R is a fixed, vitreous enamel power resistor from the 270 series, designed for high-power applications. It provides a resistance of 25Ω with a ±5% tolerance and is rated for 100 watts of power in free air at 25°C. This component features all-welded construction with a tubular ceramic core, solder-coated radial lug terminals, and a rugged, flame-resistant vitreous enamel coating. The hollow core design allows for secure mounting, making it suitable for rugged industrial applications requiring reliable power dissipation.
