Metalohm Wirewound Radial Terminal Resistors Ohmite Metalohm Wirewound Radial Terminal Resistors are flameproof, inorganic devices that offer a higher power rating due to heatsink capacity. The Metalohm Series Resistors from Ohmite have an all-welded, high surge construction with a resistance range from 0.05Ω to 100KΩ. Options for the Metalohm series include terminal sleeves to increase the dielectric strength and maximize creepage distances, non-inductive versions (Aryton-Perry windings), a multitude of terminal choices, and tapped models.
