The **ATS-16E-89-C2-R0** is a specific part number for a high-performance **heat sink** manufactured by Advanced Thermal Solutions, Inc. (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. | | **Series** | pushPIN™ HS | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Spring-loaded) | | **Dimensions (L x W x H)** | 35mm x 35mm x 30mm | | **Thermal Resistance** | 3.94 °C/W (at 100 LFM) | | **Flow Direction** | Vertical / Omni-directional (Pin Fin) | --- ### 2. Breakdown of the Part Number The part number follows a specific nomenclature that describes its physical and thermal characteristics: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **16**: Refers to the specific series or attachment style. * **E**: Specific configuration code. * **89**: The specific model/design dimensions within the series. * **C2**: Indicates the material and thermal interface material (TIM). In this case, it usually implies **T766** (a high-performance phase-change material). * **R0**: RoHS compliance status. --- ### 3. Key Electronic Functions While the heat sink itself is a passive mechanical component, its "electronic" role is critical for the stability of the circuit: 1. **Thermal Management**: It prevents the junction temperature of a semiconductor from reaching its thermal shutdown point. 2. **Push-Pin Attachment**: The "16E" designation typically includes a push-pin with a specific spring force. This ensures consistent pressure between the heat sink and the chip, which is vital for the efficiency of the Thermal Interface Material (TIM). 3. **Cross-Cut Pin Fin Design**: Unlike straight fins, the pin-fin design allows for air to enter from any direction (omni-directional), making it ideal for crowded PCB layouts where airflow direction might be inconsistent. --- ### 4. Typical Applications * **BGA (Ball Grid Array) Cooling**: Used for high-speed processors and chipsets. * **Embedded Systems**: Providing cooling in tight enclosures. * **Telecommunications**: Cooling for signal processing components.
