## Electronic Specifications: ATS-15D-121-C2-R0 The **ATS-15D-121-C2-R0** is a high-performance **Heat Sink** assembly designed by Advanced Thermal Solutions (ATS). It is specifically engineered for cooling electronic components such as CPUs, GPUs, or FPGAs that generate significant heat. --- ### 1. General Specifications This part belongs to the **pushPIN™** line, known for its secure and easy installation system. | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-15D-121-C2-R0 | | **Thermal Resistance** | 9.48°C/W (Unducted Flow @ 100 LFM) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | --- ### 2. Physical Dimensions Precision in dimensions is critical for ensuring the heat sink fits within the PCB layout without interfering with surrounding components. * **Length:** 45.00 mm * **Width:** 45.00 mm * **Height:** 10.00 mm (Low Profile) * **Pitch (Fin Style):** Fine Pitch * **Pattern:** Cross-cut --- ### 3. Thermal Performance Metrics Thermal resistance indicates how efficiently the heat sink moves heat away from the component. Lower values are better. | Air Velocity (LFM) | 100 (0.5 m/s) | 200 (1.0 m/s) | 300 (1.5 m/s) | 400 (2.0 m/s) | | :--- | :--- | :--- | :--- | :--- | | **Unducted Flow (°C/W)** | 9.48 | 5.06 | 3.89 | 3.34 | | **Ducted Flow (°C/W)** | 4.39 | 3.24 | 2.74 | 2.44 | --- ### 4. Key Electronic Features * **Thermal Interface Material (TIM):** This specific model comes pre-applied with **T766**, a high-performance thermal grease that ensures optimal heat transfer between the chip and the aluminum base. * **Push-Pin Attachment:** The use of a brass/plastic push-pin with a stainless steel spring provides a specific, consistent pressure to the component, preventing mechanical damage while maintaining thermal contact. * **Low Profile:** The 10mm height makes it ideal for dense electronic enclosures or 1U server racks where vertical space is limited. --- ### 5. Application Code (Example) While a heat sink is a mechanical part, engineers often use Python or Excel scripts to calculate the required thermal resistance ($R_{th}$) for their specific IC. ```python # Simple Thermal Calculation power_dissipation = 5.0 # Watts max_junction_temp = 85.0 # Celsius ambient_temp = 35.0 # Celsius # Required Resistance = (T_junction - T_ambient) / Power required_resistance = (max_junction_temp - ambient_temp) / power_dissipation print(f"Required Resistance: {required_resistance} °C/W") # Result: 10.0 °C/W. # Since ATS-15D-121-C2-R0 is 9.48 °C/W, it is suitable for this application. ```
