Technical Specifications The following table highlights the critical mechanical and thermal properties of this specific part number: | Property | Description / Value | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-21A-159-C2-R0 | | **Dimensions** | 45mm x 45mm x 20mm | | **Material** | Aluminum (Anodized Blue) | | **Fin Style** | Straight Fin | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Electronic Features While the part itself is passive (it does not require electricity), its design is optimized for electronic integration: * **Push-Pin Attachment:** The "21A" series utilizes a plastic push-pin and spring mechanism. This ensures a consistent pressure (load) on the electronic chip, which is vital for maintaining high thermal conductivity without cracking the silicon die. * **Thermal Resistance:** This heat sink is engineered for "forced air" environments. It significantly lowers the thermal resistance between the component junction and the ambient air, preventing thermal throttling in high-speed processors. * **Pre-Applied TIM:** The "C2" designation often refers to the inclusion of a high-performance thermal interface material (T766), which fills microscopic air gaps between the heat sink and the electronic component. * **Aluminum 6063:** The use of 6063 aluminum alloy provides a balance of thermal conductivity and structural rigidity, essential for protecting sensitive PCB traces from physical stress. --- ### 3. Application Use Cases This part is commonly used in the following electronic sectors: 1. **Telecommunications:** Cooling of high-speed network switches and routers. 2. **Embedded Systems:** Industrial PCs where space is limited but heat output is high. 3. **Power Electronics:** Dissipating heat from large MOSFET arrays or voltage regulators. --- ### 4.
