The **ATS-08A-46-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions, Inc. (ATS)*. It belongs to the **pushPIN™** series, designed for secure and efficient cooling of electronic components like CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The following table highlights the core physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25.00mm x 25.00mm x 25.00mm | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance (Unducted)** | 11.57 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 4.41 °C/W @ 100 LFM | | **Pitch** | Fine Pitch | --- ### 2. Electronic/Mechanical Components While the heat sink itself is a passive mechanical part, its "electronic" utility comes from the attachment system and its role in the circuit assembly: #### A. The Heat Sink Body * **Fin Design:** Uses a high-density "Fine Pitch" fin pattern. This increases the surface area for heat dissipation without significantly increasing the footprint on the PCB. * **Material Conductivity:** Made of AL6063 aluminum, which offers high thermal conductivity to pull heat away from the semiconductor die rapidly. #### B. The pushPIN™ Attachment System * **Push Pins:** Made of nylon or brass, these provide the mechanical force to hold the heat sink against the chip. * **Springs:** Specifically calibrated (the "C2" in the part number often denotes a specific spring tension) to provide precise "Firmness" or pressure, ensuring optimal **TIM (Thermal Interface Material)** contact without cracking the silicon die. #### C. Thermal Interface Material (TIM) * The "R0" suffix typically indicates that the part comes pre-applied with a high-performance **Phase Change Material** or thermal grease. This fills microscopic air gaps between the heat sink and the electronic component to lower thermal resistance. --- ### 3. Application Use Cases This specific part is used in environments where PCB space is limited but heat density is high: 1. **Telecommunications:** Cooling of small signal processors. 2. **Embedded Systems:** Industrial PCs where vertical clearance (25mm) is available. 3. **Power Supplies:** Cooling of MOSFETs or voltage regulators. ---
