The **ATS-05F-91-C3-R0** is a specific electronic component categorized as a **High-Performance Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It is part of the "push-pin" series designed for cooling processors or high-heat electronic components on a PCB. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific model: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 6.89° C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 40mm x 40mm x 10mm | | **Weight** | ~45 grams | --- ### 2. Key Design Features This part is engineered for efficient heat dissipation in compact spaces: * **Fin Profile:** It utilizes a **Fine Pitch** fin design. This increases the surface area available for convection, making it ideal for high-density electronic assemblies. * **Push-Pin Attachment:** The `-R0` designation indicates a hardware set that includes plastic push-pins and springs. This provides consistent pressure for the thermal interface material (TIM) and allows for secure mounting through pre-drilled holes in the PCB. * **Thermal Interface Material (TIM):** Typically, these units come with a pre-applied phase-change material (like T766) on the base to ensure a low-resistance thermal path between the chip and the aluminum. --- ### 3. Application Use Cases The ATS-05F-91-C3-R0 is commonly used in the following environments: 1. **Networking Hardware:** Cooling ASICs in routers and switches. 2. **Embedded Systems:** Industrial PCs where vertical clearance is limited (only 10mm high). 3. **Power Supplies:** Managing heat for MOSFETs or voltage regulators. --- ### 4.
