The **ATS-12B-94-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 integrated circuits (ICs) like CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance** | 4.49°C/W @ 200 LFM | | **Dimensions (L x W x H)** | 40mm x 40mm x 25mm | | **Fin Style** | Straight Fin | --- ### 2. Physical Design Components * **Heat Sink Base:** A 40x40mm flat surface that makes direct contact with the electronic component. It is usually paired with a **Thermal Interface Material (TIM)** to fill microscopic air gaps. * **Straight Fins:** The vertical "fins" increase the surface area of the aluminum. This allows moving air (convection) to carry heat away from the component more efficiently. * **Push-Pin Mechanism:** Unlike adhesive-based heat sinks, this uses spring-loaded plastic pins that snap into pre-drilled holes on the PCB. This provides consistent pressure and a more secure mechanical attachment. --- ### 3. Thermal Performance Profile Thermal resistance measures how effectively the part moves heat. Lower numbers are better. Performance varies based on airflow (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (Natural)** | 6.67 | | **200 (Low Fan)** | 4.49 | | **300 (Med Fan)** | 3.59 | | **400 (High Fan)** | 3.09 | --- ### 4. Typical Applications This specific size and mounting style are commonly found in: * **Networking Hardware:** Routers, switches, and high-speed modems. * **Industrial PCs:** Embedded systems where vibration resistance (provided by push-pins) is required. * **Power Supplies:** Cooling voltage regulators or power transistors. ---
