### Technical Overview of ATS-04B-183-C2-R0 The **ATS-04B-183-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the **pushPIN™** series, designed to provide efficient thermal management for electronic components such as processors, ASICs, and FPGAs. --- ### Key Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Fin Type** | Fine-Pitch (Cross-Cut) | | **Thermal Resistance (Unducted)** | 5.37 °C/W @ 100 LFM | | **Overall Dimensions** | 40.00mm x 40.00mm x 20.00mm | | **Mounting Hole Pattern** | 33.00mm x 33.00mm | --- ### Detailed Component Analysis #### 1. Thermal Performance The "C2" in the part number indicates the specific thermal performance grade. This heat sink is designed for **forced air cooling** environments. The cross-cut fin design increases the surface area and creates turbulence in the airflow, which enhances heat dissipation compared to standard straight-fin designs. #### 2. Mechanical Design (pushPIN™ System) The "04B" designation refers to the specific pushPIN™ attachment mechanism. - **Spring Loading:** It uses a brass or plastic push-pin with a stainless steel spring. - **Constant Pressure:** This ensures uniform pressure across the thermal interface material (TIM), preventing "hot spots." - **Ease of Assembly:** It allows for quick installation on pre-drilled PCBs without the need for complex mounting brackets. #### 3. Material and Coating - **Aluminum (AL6063):** Chosen for its excellent thermal conductivity and lightweight properties. - **Blue Anodized Finish:** This is not just aesthetic; anodizing protects the aluminum from corrosion and slightly improves radiant heat transfer. --- ### Dimensioning Reference | Dimension | Value (mm) | | :--- | :--- | | **Length (A)** | 40.00 | | **Width (B)** | 40.00 | | **Height (C)** | 20.00 | | **Pitch (E)** | 33.00 | | **Pitch (F)** | 33.00 | --- ### Usage Context This specific heat sink is typically used in: * **Networking Equipment:** Switches and routers where airflow is controlled. * **Industrial PCs:** For cooling high-speed logic controllers. * **Embedded Systems:** Where space is constrained but thermal loads are high.
