Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Category** | Heat Sink | | **Mounting Style** | pushPIN™ (Spring-loaded) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance (Flowing)** | 11.74 °C/W @ 100 LFM | | **Thermal Resistance (Static)** | 25.00 °C/W | | **Dimensions (L x W x H)** | 25mm x 25mm x 25mm | | **Attachment Type** | Push-pin with Brass/Plastic springs | --- ### 2. Component Design Details #### A. The pushPIN™ Attachment System One of the defining electronic-mechanical parts of this unit is the **pushPIN™** system. Unlike adhesive-based heat sinks, this uses a spring-loaded mechanism that ensures: * **Optimal Pressure:** Provides a consistent force against the electronic component for maximum thermal transfer. * **Reliability:** Prevents the heat sink from shifting or falling off due to vibration or thermal expansion. * **Serviceability:** Allows for easy removal and re-application of thermal paste. #### B. Fin Configuration (High Flow) The "H" in the part number indicates a **High-Flow** fin pattern. This is an electronic cooling strategy where the fins are spaced to minimize pressure drop while maximizing surface area. This is ideal for systems with concentrated air cooling. #### C. Thermal Interface Material (TIM) The unit typically comes with **pre-applied thermal interface material**. This is a critical "part" of the assembly that fills microscopic air gaps between the chip surface and the aluminum base, significantly reducing thermal resistance. --- ### 3. Usage Context in Electronics In an electronic circuit, the ATS-19H-46-C2-R0 serves as a **Passive Thermal Management** device. It is most commonly found in: 1. **Network Switches:** Cooling high-speed processing chips. 2. **Embedded Systems:** Industrial PCs where space is limited but heat density is high. 3. **Power Supplies:** Cooling MOSFETs or Voltage Regulators. --- ### 4.
