The **ATS-04G-64-C2-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS)** heat sink designed for cooling integrated circuits (ICs) and other electronic components. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by Advanced Thermal Solutions. Below is the breakdown of its physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Push-Pin Heat Sink | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 45mm x 45mm x 20mm | | **Fin Style** | Straight Fin | | **Attachment Method** | Push-Pin (Brass) with Compression Spring | | **Thermal Resistance** | ~3.39 °C/W @ 100 LFM | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Electronic Functions While the heat sink itself does not carry current, it is a critical "passive" electronic part required for the stability of active components: * **Heat Dissipation:** It increases the surface area of high-heat components (like CPUs, FPGAs, or MOSFETs) to allow air to carry away heat more efficiently. * **Thermal Protection:** By maintaining the junction temperature ($T_j$) of a semiconductor below its maximum rating, it prevents "thermal runaway" or permanent silicon damage. * **Performance Stability:** Many modern chips use "thermal throttling" (slowing down clock speeds when hot). This part ensures the electronics can run at maximum frequency for longer periods. --- ### 3. Attachment Mechanism The **"Push-Pin"** system is a mechanical design used on Printed Circuit Boards (PCBs): 1. **Holes:** The PCB must have pre-drilled holes to accommodate the pins. 2. **Spring Tension:** The built-in springs provide consistent pressure, ensuring the base of the heat sink makes perfect contact with the electronic chip. 3. **TIM:** The pre-applied T766 phase-change material fills microscopic air gaps between the chip and the aluminum to maximize heat transfer. --- ### 4. Common Applications This specific size and mounting style are typically found in: * Network Switches and Routers. * Embedded Computing modules. * Power Supply units (PSUs). * Telecommunications equipment.
