The OHMITE AH50600V05000FE is a heatsink specifically engineered for use with Arcol and Ohmite aluminum housed resistors. Each heatsink is custom-tailored to a specific resistor size, providing a complete thermal management solution. Constructed from durable aluminum alloy 6063-T5, these heatsinks offer excellent heat dissipation. They are typically supplied unfinished and degreased, with other finishes available upon request. The heatsink is designed for vertical mounting, and while horizontal mounting is acceptable, it may result in a slight performance degradation.
