The **ATS-08B-78-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions, Inc.** It is designed specifically for thermal management in electronic systems, particularly for cooling surface-mount components like CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25mm x 25mm x 25mm | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 7.71°C/W (Unducted Flow @ 100 LFM) | | **Fin Style** | Straight Fin | | **Compliance** | RoHS-6 and REACH Compliant | --- ### 2. Key Design Features #### A. pushPIN™ Attachment System This heat sink uses a specialized **pushPIN™** mechanism. This is superior to traditional adhesive tapes because: * It provides a **precise mounting pressure** to optimize thermal interface material (TIM) performance. * It allows for secure attachment in high-vibration environments. * The system includes a pre-drilled hole pattern for easy installation onto a PCB. #### B. Straight Fin Geometry The "Straight Fin" design is optimized for **forced air cooling**. While cross-cut fins are better for omnidirectional airflow, straight fins offer lower pressure drop and are highly efficient when the airflow direction is known and consistent. #### C. Thermal Interface Material (TIM) The "R0" suffix typically denotes that the part comes with **no pre-applied thermal interface material**, or it uses a standard high-performance thermal pad. This allows engineers to select the specific TIM (grease, pad, or phase-change material) that fits their power density requirements. --- ### 3. Thermal Performance Profile The effectiveness of the ATS-08B-78-C2-R0 depends heavily on the velocity of the air (measured in Linear Feet per Minute - LFM): | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 7.71 | | 300 (1.5 m/s) | 3.12 | | 500 (2.5 m/s) | 2.30 | | 700 (3.5 m/s) | 1.94 | --- ### 4. Applications * **Networking:** Switches and routers where high-speed processors generate localized heat. * **Embedded Computing:** Industrial PCs and automation controllers. * **Power Electronics:** Cooling MOSFETs or power conversion modules.
