The **ATS-18A-151-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push pin" series designed to provide efficient cooling for electronic components like CPUs, GPUs, and other high-heat surface-mount devices. --- ### ## Technical Specifications The following table outlines the physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Mounting Style** | Push-Pin (Plastic) | | **Fin Type** | Fine Pitch (Straight) | | **Dimensions** | 35mm x 35mm x 20mm | | **Thermal Resistance** | 3.91°C/W @ 200 LFM | | **Interface Material** | T766 (Thermal Tape) | --- ### ## Design Characteristics ### 1. Thermal Efficiency The "Fine Pitch" design provides a high surface area relative to its footprint. This makes it ideal for **forced air cooling** environments (where a fan is present), as the narrow spacing between fins maximizes heat dissipation. ### 2. Attachment Mechanism The **"R0"** suffix indicates the use of plastic push-pins and a brass spring. * **Ease of Assembly:** No tools are required for installation. * **Consistency:** The spring ensures constant pressure between the heat sink and the component, optimizing thermal transfer. * **Safety:** The plastic pins are non-conductive, reducing the risk of electrical shorts on the PCB. ### 3. Material and Coating * **Aluminum:** Chosen for its excellent thermal conductivity-to-weight ratio. * **Blue Anodizing:** This is not just aesthetic; the anodized layer increases the emissivity of the surface, slightly improving radiant heat transfer and providing corrosion resistance. ### 4. Thermal Interface Material (TIM) This specific model comes pre-applied with **T766 thermal tape**. This simplifies the manufacturing process by eliminating the need for manual application of thermal grease. --- ### ## Applications * **Telecommunications:** Cooling of high-speed networking chips. * **Embedded Systems:** Industrial PCs and controllers. * **Power Electronics:** Voltage regulators and high-density power modules.
