Outstanding Heatsink Aluminum Housed Wirewound Power Precision Resistors (AH). 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.
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.
