The **ATS-P1-91-C3-R0** is a high-performance heat sink manufactured by Advanced Thermal Solutions (ATS). It belongs to the **maxiFLOW™** series, specifically designed for cooling electronic components such as CPUs, GPUs, FPGAs, and ASICs where space is limited but thermal demands are high. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Characteristic | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 40mm x 40mm x 10mm | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | 6.96°C/W (at 200 LFM) | | **Fin Style** | Straight Fin | | **Thermal Interface Material (TIM)** | T412 (Standard Phase Change) | --- ### 2. Key Electronic Features #### A. Thermal Management Efficiency The "C3" in the part number indicates a specific thermal performance profile. It uses a **tapered fin design** that maximizes surface area while minimizing pressure drop. This is critical for electronic stability, as keeping the junction temperature low extends the lifespan of the semiconductor. #### B. pushPIN™ Attachment System Unlike adhesive-based heat sinks, this part uses the **pushPIN™** system. For electronic design, this offers several advantages: * **Uniform Pressure:** Ensures consistent contact between the die and the heat sink. * **Reliability:** Mechanical fasteners are more resistant to shock and vibration than thermal tape. * **Serviceability:** Allows for the heat sink to be removed and re-installed during board repairs without damaging the PCB. #### C. T412 Thermal Interface Material The unit comes pre-applied with **T412**, a high-performance thermal pad/paste. This fills the microscopic air gaps between the component and the heat sink, significantly reducing thermal impedance. --- ### 3. Application Use Cases This specific model is typically integrated into the following electronic systems: * **Telecommunications:** High-speed routers and switches. * **Industrial PC:** Embedded controllers that operate in harsh environments. * **Power Electronics:** Voltage regulators that generate significant heat in a small footprint. ---
