The **ATS-19H-101-C3-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) to prevent overheating. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics: | Specification | Details | | :--- | :--- | | **Component Type** | Passive Heat Sink | | **Material** | Aluminum (High Thermal Conductivity) | | **Finish** | Blue Anodized | | **Dimensions** | 45mm x 45mm x 30mm | | **Thermal Resistance** | ~6.77°C/W (Unducted Flow @ 200 LFM) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **TIM (Thermal Interface Material)** | T412 (Double-sided adhesive/pad) | --- ### 2. Design Features * **XC Cut (Cross-Cut) Pattern:** The heat sink features a "straight-fin" design with cross-cuts. This allows for multi-directional airflow, making it effective even if the air direction is not perfectly aligned with the fins. * **pushPIN™ Attachment:** This is a specialized mounting mechanism that uses a brass or plastic pin and a stainless steel spring. It ensures a consistent pressure (7-10 lbs) against the component for optimal heat transfer. * **T412 Thermal Interface:** The base comes pre-applied with a thermal pad. This fills microscopic air gaps between the CPU/GPU and the heat sink base to lower thermal resistance. --- ### 3. Application Use Cases This specific heat sink is typically found in hardware where active cooling (fans) is present but localized heat dissipation is required for individual chips: 1. **Networking Hardware:** High-speed routers, switches, and gateways. 2. **Power Electronics:** Voltage regulators and power modules. 3. **Industrial Computing:** Embedded systems and Single Board Computers (SBCs). 4. **FPGA/ASIC Cooling:** Providing thermal relief for custom-coded processors. --- ### 4. Thermal Performance Overview The efficiency of the ATS-19H-101-C3-R0 is highly dependent on the Airflow (measured in Linear Feet per Minute - LFM): ```markdown Airflow (LFM) | Thermal Resistance (°C/W) --------------|------------------------- 200 (1.0 m/s) | 6.77 400 (2.0 m/s) | 2.50 600 (3.0 m/s) | 1.80 ``` *Note: Lower thermal resistance values indicate better cooling performance.* ---
