The **ATS-08D-157-C2-R0** is a high-performance heat sink manufactured by *Advanced Thermal Solutions (ATS)*, specifically part of the **pushPIN™** series. These components are critical in electronics for thermal management, preventing semiconductors from overheating. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 3.35°C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W)** | 40.00 mm x 40.00 mm | | **Height** | 30.00 mm | | **Fin Pattern** | XC-CUT (Cross-cut) | --- ### 2. Key Electronic Functions In an electronic circuit, this heat sink serves as a **passive cooling component**: * **Heat Dissipation:** It increases the surface area of a hot component (like a CPU, GPU, or MOSFET), allowing heat to transfer into the ambient air more efficiently. * **Thermal Interface:** It is designed to be used with a Thermal Interface Material (TIM), such as thermal grease or a pad, to bridge the microscopic air gaps between the chip and the heat sink. * **Thermal Stability:** By maintaining a lower operating temperature, it prevents "thermal throttling" and extends the MTBF (Mean Time Between Failures) of the electronic assembly. --- ### 3. Mechanical Design Features * **Push-Pin Attachment:** This model uses a flexible, spring-loaded mechanism. This ensures consistent pressure across the component for optimal heat transfer without over-stressing the PCB. * **Cross-Cut Fin Design:** The "XC-CUT" fin profile allows for airflow from any direction, making it highly versatile for compact enclosures where airflow might be unpredictable. * **Pre-Applied TIM:** Most variants in this series come with pre-applied high-performance thermal interface material to simplify assembly. --- ### 4. Typical Applications * Embedded systems and Single Board Computers (SBCs). * High-speed networking equipment (routers, switches). * Power supplies and industrial controllers. * LED lighting thermal management.
