AH Aluminum Housed Power Resistors
Aluminum Housed Power Resistors
Outstanding Heatsink Aluminum Housed Power Resistor (AH)
Preview Token Electronics aluminum chassis mount units are designed for maximum heat dissipation mounting solidly to metal chassis surface for maximum heat transfer. AH series are outstanding for their high power dissipation with precision tolerances in minimum physical sizes. Lower hot spot ratings due to exclusive complete encapsulation of element within anodized aluminum body. AH series high-performance welded construction throughout assures long stable load life with threaded heavy stud axial-terminals. Materials : Encapsulant: S: Silicone, C: Cement; End caps: Stainless steel. Core: Ceramic steatite or alumina. Housing: Aluminum with hard anodic coating. Element: Copper-nickel alloy, nickel-chrome alloy or manganese copper. Standard Terminals: 5~50 W Tinned terminals, 100~250 W Threaded terminals. General Specification : Ayrton Perry type non-inductive winding is available. When required add "N" to the part number. Standard winding & non-inductive winding avaiable. High power rating, strong construction, small size, and ultra precision. Aluminum housing allows chassis mounting and provides heat sink capability The AH Series is RoHS compliant and lead free. For non-standard technical requirements and custom special applications, please contact us to discuss the details.
