Vishay Industrial Power Through-Hole Wirewound Resistors

Vishay Industrial Power Through-Hole Wirewound Resistors enamel or silicone coating has a power rating between 8W to 1500W. These wirewound resistors are designed to meet heavy-duty requirements where space is constrained and are made with flameproof inorganic compounds. Industrial Power Through-Hole Wirewound Resistors offer heat transfer increased by the use of thermally conductive grease or epoxy which operates at a temperature range from -55°C to +415°C. Vishay's Industrial Resistors find applications in audio-video equipment, current-voltage balancing, telephone switching systems, and industrial automation.
