The **ATS-16B-121-C2-R0** is a high-performance electronic component specifically categorized as a **Heat Sink**. It is manufactured by *Advanced Thermal Solutions (ATS)* as part of their "push-pin" series designed for board-level cooling of electronic components like CPUs, GPUs, or FPGAs. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics. Here is the breakdown: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance** | 9.48°C/W @ Unducted Flow | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Fin Style** | Straight Fin | | **RoHS Status** | Compliant | --- ### 2. Key Components & Design Electronic parts like this heat sink rely on three main design elements to function effectively: * **The Base (45x45mm):** The flat surface that makes direct contact with the electronic chip. It is designed to be perfectly flat to minimize air gaps. * **The Fins:** The vertical "walls" increase the surface area of the aluminum. This allows more air to pass over the metal, carrying away heat via convection. * **The Push-Pin Mechanism:** Instead of using messy adhesives or permanent solder, this part uses spring-loaded plastic pins. These pins snap into pre-drilled holes in the PCB (Printed Circuit Board) to provide consistent downward pressure. --- ### 3. Electronic Performance Metrics In the context of electronics, thermal management is measured by **Thermal Resistance ($R_{th}$)**. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 (1.0 m/s) | 5.04 | | 400 (2.0 m/s) | 3.51 | | 600 (3.0 m/s) | 2.85 | *Note: As the air speed (LFM) increases, the resistance drops, meaning the electronic component stays cooler.* --- ### 4. Typical Applications * **Embedded Systems:** Cooling microcontrollers on industrial motherboards. * **Networking:** Cooling ASICs inside routers or switches. * **Power Supplies:** Managing heat for voltage regulators or power transistors.
