The **ATS-19H-76-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 components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications The part number itself contains encoded information about the dimensions, material, and performance characteristics. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 25mm x 25mm x 15mm | | **Pitch** | Fine-Pitch Fin Pattern | | **Thermal Resistance** | 11.58 °C/W (at 100 LFM) | --- ### 2. Key Physical Components #### A. The Fin Array This part utilizes a **mini-fan/straight fin** design. The high density of fins increases the surface area exposed to the air, which allows for better heat transfer via convection. #### B. The Push-Pin Attachment Instead of using adhesive tape or thermal glue, this part uses the **pushPIN™** system. * **Mechanism:** Two pins with internal springs. * **Benefit:** Provides consistent pressure (preload) against the electronic component, ensuring maximum thermal contact while allowing for easy installation and removal. #### C. Thermal Interface Material (TIM) The "R0" at the end of the part number typically indicates that it comes pre-applied with a high-performance **Thermal Interface Material** (usually a phase-change material or grease). This fills microscopic air gaps between the heat sink and the chip. --- ### 3. Electronic Application This specific heat sink is categorized as "Small Form Factor." It is commonly used on: 1. **Network Switches/Routers:** For cooling ASICs or localized processors. 2. **Embedded Systems:** Industrial PCs where space is limited but heat density is high. 3. **Voltage Regulators:** To prevent thermal throttling in power delivery circuits. --- ### 4. Performance Metrics Thermal performance depends heavily on airflow (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 11.58 | | 300 (1.5 m/s) | 4.51 | | 500 (2.5 m/s) | 3.23 | *[Note: Lower °C/W values indicate better cooling efficiency.]*
