## Electronic Component Overview: ATS-20B-79-C2-R0 The **ATS-20B-79-C2-R0** is not an active electronic integrated circuit (IC) or sensor; rather, it is a high-performance **Heat Sink** assembly designed for thermal management of electronic components like CPUs, GPUs, FPGAs, or power transistors. It is manufactured by **Advanced Thermal Solutions (ATS)** as part of their **maxiFLOW™** product line. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | Heat Sink | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Material** | Aluminum (Black Anodized) | | **Thermal Resistance** | 26.32° C/W (Unducted Flow @ 100 LFM) | | **Dimensions (L x W x H)** | 45.00mm x 45.00mm x 20.00mm | | **Fin Style** | maxiFLOW (Tapered Fin Design) | | **Compliance** | RoHS and REACH Compliant | --- ### 2. Physical Construction & Design * **MaxiFLOW™ Fin Geometry:** The component features a unique "flared" or tapered fin design. This geometry is engineered to maximize surface area and increase turbulence in the airflow, which significantly improves the convection cooling efficiency compared to standard straight-fin heat sinks. * **pushPIN™ Attachment:** The "R0" suffix indicates the inclusion of the pushPIN™ mounting system. This consists of a brass or plastic pin and a stainless steel spring that ensures a precise, high-pressure contact between the heat sink and the electronic component (TIM - Thermal Interface Material included). * **Aluminum Body:** The use of aluminum provides a lightweight solution with high thermal conductivity, while the **Black Anodized** finish increases thermal emissivity, helping radiation cooling. --- ### 3. Thermal Performance Metrics The efficiency of this part depends heavily on the airflow (LFM - Linear Feet per Minute) within the electronic enclosure: | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (0.5 m/s)** | 26.32 | | **200 (1.0 m/s)** | 11.69 | | **400 (2.0 m/s)** | 7.07 | | **600 (3.0 m/s)** | 5.63 | --- ### 4. Typical Applications This part is used to protect sensitive electronic parts from overheating in the following scenarios: * **Telecommunications:** Cooling of high-speed networking chips. * **Embedded Systems:** Thermal management for industrial PC processors. * **Power Electronics:** Dissipating heat from large MOSFETs or IGBT modules. ---
