The **ATS-12D-149-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic integrated circuits (ICs), such as CPUs, GPUs, or power modules. --- ### Technical Specifications The following table outlines the physical and thermal characteristics of the device: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Base Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Plastic/Brass) | | **Thermal Resistance** | 6.21°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 35.00mm x 35.00mm | | **Height (Fin Depth)** | 20.00mm | | **Fin Pattern** | Cross-Cut (Square Fins) | --- ### Core Components and Design #### 1. The Fin Structure (Cross-Cut) Unlike standard longitudinal fins, this model uses a **cross-cut pattern**. This creates a grid of small square pillars. This design is highly effective in environments where the airflow direction might be inconsistent or "turbulent," as it allows air to enter the fin array from multiple angles. #### 2. Attachment Mechanism: pushPIN™ The "12D" designation often refers to the specific attachment kit. This part uses a spring-loaded **push-pin** system: * **Compression Spring:** Ensures constant pressure between the heat sink and the chip. * **Thermal Interface Material (TIM):** This part usually comes pre-applied with **T766** (a high-performance thermal grease) on the base to ensure there are no air gaps between the component and the sink. #### 3. Material and Finish * **Aluminum:** Chosen for its excellent thermal conductivity-to-weight ratio. * **Blue Anodized Finish:** This is not just for aesthetics; anodizing increases the surface emissivity, slightly improving radiant heat transfer and providing corrosion resistance. --- ### Part Number Breakdown (Nomenclature) To understand the specific configuration of this part: | Segment | Meaning | | :--- | :--- | | **ATS** | Manufacturer (Advanced Thermal Solutions) | | **12D** | Attachment Type (Push-pin style/Spring) | | **149** | Specific size/fin geometry code | | **C2** | Thermal Performance Level / Material Grade | | **R0** | Revision/Packaging code | --- ### Typical Applications * **Telecommunications:** Cooling of high-speed processors in routers and switches. * **Embedded Systems:** Industrial PCs where space is limited but heat density is high. * **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators.
