The part number **ATS-03D-142-C2-R0** refers to a high-performance **heat sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push pin" heat sink series designed for cooling electronic components like CPUs, GPUs, and other integrated circuits. ### 1. Technical Specifications Below are the key mechanical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push Pin (with compression springs) | | **Dimensions** | 30mm x 30mm x 15mm | | **Thermal Resistance** | 1.90°C/W (at 200 LFM) | | **Fin Style** | Straight Fin (Extrusion) | | **Compliance** | RoHS Compliant | --- ### 2. Breakdown of the Part Number The nomenclature for ATS heat sinks typically follows a specific logic: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **03**: Series indicator (Push-pin type). * **D**: Material/Style indicator (Aluminum). * **142**: Size/Geometry code (30mm x 30mm). * **C2**: Thermal Interface Material (TIM) and Finish code (usually T766 phase change material or similar). * **R0**: Revision/Packaging code. --- ### 3. Key Component Features #### A. Thermal Interface Material (TIM) The "C2" suffix indicates that the heat sink comes pre-applied with a high-performance **Thermal Interface Material**. This eliminates the need for manual application of thermal paste and ensures consistent heat transfer between the chip and the aluminum base. #### B. Push Pin Mounting System The unit uses a mechanical push-pin system with a spring. This provides: 1. **Constant Pressure:** Ensures the heat sink stays flat against the component. 2. **Tool-less Installation:** Can be installed manually by pushing the pins through pre-drilled holes in the PCB. 3. **Vibration Resistance:** The spring tension helps prevent the heat sink from shifting during transport or operation. #### C. Straight Fin Design The fins are oriented in a straight pattern, making this part ideal for **forced convection** (airflow directed by a fan). The aluminum construction provides a balance between lightweight design and efficient heat dissipation. --- ### 4. Applications This specific heat sink is commonly found in: * **Networking Equipment:** Routers and switches. * **Embedded Systems:** Industrial PCs and controllers. * **Power Electronics:** Cooling MOSFETs or small voltage regulators. ---
