Technical Specifications The following table summarizes the primary physical and thermal characteristics of this part: | Characteristic | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 36.83mm x 53.0mm x 17.78mm | | **Thermal Resistance** | 17.42° C/W (at 100 LFM) | | **Airflow Path** | High-performance MaxiFLOW (spread fin) | | **TIM (Thermal Interface Material)** | T766 (Pre-applied) | --- ### 2. Key Component Features #### A. The Fin Design (maxiFLOW™) Unlike standard extruded heat sinks, the ATS-05D-33-C2-R0 uses a spread-fin geometry. This increases the surface area and creates more turbulence in the airflow, which significantly enhances heat dissipation in forced-convection environments. #### B. The pushPIN™ Attachment System This part uses a proprietary attachment mechanism consisting of: * **Compression Springs:** Ensure even pressure across the surface of the component (e.g., a BGA chip or FPGA). * **Plastic/Brass Pins:** Designed to fit into pre-drilled holes in the PCB, providing a secure mechanical fit that is resistant to shock and vibration. #### C. Thermal Interface Material (TIM) The base comes pre-applied with **T766**, a high-performance thermal pad/grease. This ensures that microscopic air gaps between the heat sink and the electronic component are filled, minimizing thermal contact resistance. --- ### 3. Common Applications This heat sink is typically found in hardware where localized high-heat generation occurs: * **Networking Equipment:** High-speed routers and switches. * **Telecommunications:** Base stations and signal processing units. * **Embedded Systems:** Industrial PCs and single-board computers. * **Integrated Circuits:** Specifically for BGAs (Ball Grid Arrays) and FPGAs. --- ### 4. Thermal Performance Comparison Thermal resistance decreases as airflow (measured in Linear Feet per Minute - LFM) increases: | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100** | 17.42 | | **300** | 7.42 | | **500** | 5.34 |
