The OHMITE AH10928V10000JE is a heatsink specifically engineered for use with Arcol/Ohmite aluminum housed resistors. Each heatsink is characterized and custom-tailored to a specific resistor size, ensuring optimal thermal performance. Constructed from aluminum alloy 6063-T5, these heatsinks are typically unfinished and degreased, with other finishes available upon request. Modifications such as screw holes, bolt patterns, and milling are also possible to meet specific customer requirements. The heatsink's thermal resistance is optimized for vertical orientation in natural convection, and horizontal mounting is acceptable with fins in the upward position, resulting in a slight performance degradation.
