The **ATS-04H-91-C1-R0** is a high-performance **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **pushPIN™** series, designed specifically for cooling electronic components like CPUs, GPUs, and other integrated circuits. --- ### 1. Technical Specifications Below are the primary mechanical and thermal properties of the device: | Property | Description | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Plastic Pegs with Springs) | | **Fin Type** | Fine Pitch (Straight Fins) | | **Thermal Resistance** | 21.86 °C/W (at 100 LFM) to 1.73 °C/W (at 700 LFM) | | **Dimensions** | 40mm x 40mm x 10mm | --- ### 2. Physical Design Components * **The Heat Sink Body:** Constructed from high-quality aluminum for excellent thermal conductivity. The "91" in the part number indicates the specific fin geometry and height (10mm). * **The Interface Material (TIM):** This part usually comes with pre-applied **T766** thermal interface material (phase change material) on the base to ensure maximum heat transfer from the component to the sink. * **The Attachment System (pushPIN™):** * **Springs:** Provides consistent pressure to ensure the base stays in contact with the chip. * **Pins:** Designed for easy installation into pre-drilled holes on a PCB (Printed Circuit Board). --- ### 3. Thermal Performance (Airflow) The efficiency of this part is highly dependent on the velocity of air (measured in Linear Feet per Minute - LFM) passing through the fins: | Air Velocity (LFM) | 100 | 300 | 500 | 700 | | :--- | :--- | :--- | :--- | :--- | | **Thermal Resistance (°C/W)** | 21.86 | 4.39 | 2.50 | 1.73 | --- ### 4. Applications This electronic part is typically found in: 1. **Network Switches/Routers:** Cooling internal processors. 2. **Embedded Systems:** For compact boards where space (10mm height) is limited. 3. **Power Supplies:** Managing heat from voltage regulators. ---
