The **ATS-05D-77-C2-R0** is an electronic thermal management component, specifically a **high-performance heat sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or hardware failure. --- ### Technical Specifications The following table outlines the physical and thermal characteristics of this specific part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Material** | Aluminum (Blue Anodized) | | **Dimensions (L x W)** | 25mm x 25mm | | **Height (H)** | 20mm | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance** | 9.30°C/W (at 100 LFM) | | **Fin Pattern** | Fine Pitch (Cros-Cut) | --- ### Key Electronic & Design Features #### 1. Heat Sink Geometry The "77" in the part number indicates a specific cross-cut fin geometry. This design increases the surface area available for heat transfer and allows for omnidirectional airflow, making it effective in compact electronic enclosures where air may flow from multiple angles. #### 2. pushPIN™ Attachment System This part utilizes a specific mounting mechanism: * **Plastic Push-Pins:** These secure the heat sink to the PCB through pre-drilled holes. * **Compression Springs:** Each pin features a spring that provides precise, uniform pressure across the component surface (the TIM - Thermal Interface Material), ensuring optimal heat transfer without cracking the silicon die. #### 3. Thermal Interface Material (TIM) The "R0" suffix typically denotes that the heat sink comes with a pre-applied high-performance thermal interface material. This eliminates the need for manual application of thermal paste and ensures a low thermal resistance "bond" between the chip and the aluminum. #### 4. Material and Finish * **Aluminum:** Chosen for its balance between thermal conductivity and light weight. * **Blue Anodized Finish:** Provides a protective layer against corrosion and slightly improves radiative heat transfer. --- ### Common Applications * **Embedded Systems:** Industrial PCs and small form-factor controllers. * **Networking Gear:** Routers, switches, and high-speed modems. * **Power Electronics:** Voltage regulators and power modules that generate localized heat.
