The **ATS-11F-41-C3-R0** is a high-performance electronic thermal management component, specifically a **Pin Fin Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power semiconductors. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum (Al) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Fin Type** | Pin Fin | | **Dimensions** | 40mm x 40mm x 20mm | | **Thermal Resistance** | 10.07°C/W (at 200 LFM) | | **Thermal Interface Material (TIM)** | T412 (Non-silicone based) | --- ### 2. Key Electronic Components & Design Features #### A. The pushPIN™ Attachment System Unlike adhesive tapes that can fail over time, this part uses a mechanical **pushPIN™** system. This consists of a plastic or brass pin and a stainless steel spring. * **Purpose:** Provides a consistent, high-pressure contact between the heat sink and the electronic component, which is critical for minimizing thermal resistance. * **Integration:** Requires pre-drilled holes in the Printed Circuit Board (PCB). #### B. Pin Fin Geometry The "Pin Fin" design consists of a grid of vertical cylindrical posts rather than traditional straight fins. * **Omnidirectional Airflow:** This is crucial for electronics with unpredictable or turbulent airflow inside a chassis. Air can enter and exit the fin array from any direction. * **Low Pressure Drop:** It allows air to flow through the pins more easily, making it effective in low-velocity environments. #### C. Thermal Interface Material (T412) The part comes pre-applied with **T412**, a phase-change material. * **Function:** It fills the microscopic air gaps (voids) between the bottom of the heat sink and the top of the electronic chip. * **Benefit:** T412 is a high-performance material that provides excellent thermal conductivity while remaining stable under high temperatures. --- ### 3. Applications This part is commonly found in the following electronic systems: 1. **Telecommunications:** Cooling of high-speed networking chips and FPGA units. 2. **Embedded Systems:** Industrial PCs where mechanical vibration might loosen adhesive-mounted heat sinks. 3. **Power Supplies:** Cooling MOSFETs or Voltage Regulators (VRMs) that generate concentrated heat. ---
