The **ATS-01B-91-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) Heat Sink** designed for cooling electronic integrated circuits (ICs) and surface-mount devices. ### 1. Technical Specifications The part number follows a specific nomenclature used by Advanced Thermal Solutions. Here is the breakdown of its physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Product Type** | pushPIN™ Heat Sink Assembly | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded plastic/brass pins) | | **Dimensions (L x W x H)** | 40.00mm x 40.00mm x 10.00mm | | **Thermal Resistance** | 21.97 °C/W (at 100 LFM) | | **Flow Pattern** | Straight Fin | --- ### 2. Electronic Application & Function This component is vital for maintaining the reliability of sensitive electronic parts. Its primary functions include: * **Heat Dissipation:** It increases the surface area of a heat-generating component (like a CPU, FPGA, or GPU), allowing air to carry heat away more efficiently. * **Thermal Interface:** It is typically paired with a **Thermal Interface Material (TIM)**, such as a phase-change material or thermal pad (pre-applied as T766 in this series), to eliminate air gaps between the IC and the metal. * **Mechanical Stability:** The "pushPIN™" system provides a consistent compression force, ensuring the heat sink remains in contact with the electronic package even during mechanical vibration or thermal expansion. --- ### 3. Key Electronic Components it Protects This specific low-profile heat sink (10mm height) is commonly found in space-constrained electronics such as: 1. **Network Switches/Routers:** Cooling processors that handle high-speed data. 2. **Power Supplies:** Managing heat in MOSFETs or voltage regulators. 3. **Embedded Systems:** For industrial PCs where vertical clearance is limited. --- ### 4. Part Number Breakdown The "C2" and "R0" suffixes refer to specific material and compliance standards: * **C2:** Refers to the thermal performance tier and material (Aluminum with Blue Anodized finish). * **R0:** Indicates **RoHS compliance**, meaning the part is free from restricted hazardous substances like lead and mercury.
