Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Base Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push Pin (Plastic) | | **Thermal Resistance (Unducted)** | 7.94 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 1.62 °C/W @ 100 LFM | --- ### 2. Design and Physical Dimensions The design of the ATS-02A-89-C2-R0 focuses on maximizing surface area while maintaining a compact footprint for dense PCB layouts. * **Heat Sink Profile:** It features a **Straight-Fin** design. This allows for optimal airflow in a single direction, making it ideal for systems with chassis fans. * **Dimensions:** * **Length:** 35.00 mm * **Width:** 35.00 mm * **Height:** 20.00 mm (measured from the base to the top of the fins) * **Pitch/Pattern:** The hole pattern for the push-pin attachment is typically 40.00 mm x 40.00 mm. --- ### 3. Mounting and Thermal Interface The "C2" and "R0" designations in the part number refer to the specific configuration of the mounting hardware and the thermal interface material (TIM). 1. **Push Pin Mechanism:** It uses a spring-loaded plastic push pin. This ensures consistent pressure between the heat sink and the component, which is critical for heat transfer. 2. **Thermal Interface Material (TIM):** This specific model comes pre-applied with **T766** thermal phase change material. This eliminates the need for manual application of thermal paste and ensures high thermal conductivity. 3. **Springs:** The assembly utilizes stainless steel springs to maintain the attachment force over the life of the product. --- ### 4. Thermal Performance Comparison Performance varies significantly based on the Air Velocity (Measured in Linear Feet per Minute - LFM): | Velocity (LFM) | 100 | 200 | 300 | 400 | 500 | | :--- | :---: | :---: | :---: | :---: | :---: | | **Resistance (Unducted)** | 7.94 | 2.77 | 1.61 | 1.18 | 0.97 | | **Resistance (Ducted)** | 1.62 | 1.04 | 0.85 | 0.75 | 0.68 | ---
