The **ATS-05D-148-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. --- ## 1. Technical Specifications The part number encodes specific physical and thermal properties essential for PCB design: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions** | 35mm x 35mm x 15mm | | **Attachment Method** | Push-Pin (Plastic) with Spring | | **Thermal Resistance** | ~14.2°C/W (at low airflow) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ## 2. Key Components and Features ### A. High-Efficiency Fin Design The "148" series utilizes a **cross-cut fin pattern**. This design allows for multidirectional airflow, meaning the heat sink remains effective regardless of which direction the fan is blowing across the PCB. ### B. Push-Pin Attachment Mechanism This part uses a standardized push-pin system: * **Ease of Assembly:** No screws are required; it snaps into pre-drilled holes in the PCB. * **Constant Pressure:** The integrated springs ensure consistent contact pressure between the heat sink and the electronic component, which is vital for efficient heat transfer. ### C. Thermal Interface Material (TIM) The "C2" suffix indicates that the unit comes with **ATS-T766** pre-applied to the base. * This removes the need for manual application of thermal paste. * T766 is a high-performance phase-change material designed to fill microscopic air gaps between the component and the heat sink. --- ## 3. Thermal Performance Profile The effectiveness of this part is highly dependent on the velocity of the air (LFM - Linear Feet per Minute) within the enclosure: | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 | 8.70 | | 400 | 5.23 | | 600 | 4.32 | --- ## 4. Common Applications * **Embedded Systems:** Industrial PCs and routers. * **Power Electronics:** Voltage regulators and MOSFET modules. * **FPGA Cooling:** Providing thermal stability for Field Programmable Gate Arrays.
