The **ATS-05D-151-C1-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink**, manufactured by Advanced Thermal Solutions (ATS). It belongs to the "pushPIN™" family of thermal solutions. ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Part Number** | ATS-05D-151-C1-R0 | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Type** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 3.90 °C/W @ 100 LFM | | **Dimensions (L x W)** | 35mm x 35mm | | **Height** | 10mm | | **Fin Pattern** | Fine-Pitch (Cross-cut) | --- ### Core Electronic & Mechanical Features #### 1. Thermal Resistance Performance This part is designed to dissipate heat from surface-mount components (like CPUs, GPUs, or FPGAs). The efficiency varies based on airflow (LFM - Linear Feet per Minute): * **Unducted Flow:** 3.90 °C/W (at 100 LFM) down to 1.74 °C/W (at 700 LFM). * **Ducted Flow:** 2.35 °C/W (at 100 LFM) down to 1.43 °C/W (at 700 LFM). #### 2. pushPIN™ Attachment Mechanism Unlike adhesive-based heat sinks, this part uses a **spring-loaded pushPIN system**. * **Benefits:** Provides consistent pressure for optimal thermal interface material (TIM) performance and prevents the heat sink from shifting due to vibration or shock. * **Hardware:** It typically uses brass or plastic pins with stainless steel springs. #### 3. Fin Design (Fine-Pitch) The "Fine-Pitch" design increases the surface area available for heat transfer. The cross-cut pattern allows for multi-directional airflow, making it ideal for compact electronic enclosures where airflow direction may not be strictly linear. #### 4. Interface Material (TIM) The "R0" suffix generally indicates that the part comes with a **pre-applied Thermal Interface Material**, usually a high-performance phase-change material or thermal pad, ensuring low thermal resistance between the component and the heat sink. --- ### Application Use Cases * **Telecommunications:** Cooling of high-speed networking chips. * **Embedded Systems:** Thermal management for industrial controllers. * **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators.
