The **ATS-07F-148-C3-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the **pushPIN™** series, designed to provide efficient cooling for electronic components like CPUs, GPUs, and other high-heat surface-mount devices. ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Mounting Type** | pushPIN™ (Plastic Peg) | | **Attachment Method** | Spring-loaded push pins | | **Thermal Resistance** | 8.78°C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 35.0mm x 35.0mm x 15.0mm | | **Fin Pattern** | XC-CUT (Cross-cut) | | **Thermal Interface** | T412 (Pre-applied thermal grease) | --- ### 2. Design Breakdown #### A. The XC-CUT Fin Design The "XC-CUT" indicates a cross-cut straight fin design. This pattern allows for multi-directional airflow, making it ideal for systems where the air intake direction may be inconsistent or constrained. #### B. PushPIN™ Attachment System This part uses a specific mounting mechanism: * **Ease of Install:** No tools are required for mounting; the plastic pins snap into pre-drilled holes in the PCB. * **Compression Springs:** The springs provide precise, consistent pressure on the component, ensuring maximum contact with the thermal interface material. #### C. Thermal Performance The efficiency of this heat sink is measured by its thermal resistance (lower is better). * **At 100 LFM (Linear Feet per Minute):** 8.78°C/W * **At 500 LFM:** 2.85°C/W * The performance improves significantly as airflow (CFM) increases, indicating it is optimized for active-cooled environments. --- ### 3. Application Use Cases The ATS-07F-148-C3-R0 is commonly used in: * **Network Switches/Routers:** Cooling ASICs and chipsets. * **Power Supplies:** Managing heat for voltage regulators. * **Industrial PCs:** Compact thermal management for small-form-factor boards. --- ### 4.
