The part number **S02-07-R-98CS816** refers to a high-performance **SolderSleeve Shield Terminator** manufactured by TE Connectivity (Raychem). These components are engineered to provide a reliable, insulated, and strain-relieved electrical connection for cable shielding. --- ### 1. Component Overview The S02 series is part of the **Raychem AS83519/2** standard (specifically the M83519/2 revision). These parts are designed for high-reliability environments where electromagnetic interference (EMI) protection is critical. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Polyvinylidene fluoride (PVDF) heat-shrinkable sleeve | | **Solder Type** | Sn63 Pb37 (Lead-based) with ROL1 flux | | **Temperature Range** | -55°C to +150°C | | **Sealing** | Environmental sealing (thermoplastic inserts) | | **Pre-installed Lead** | Yes (Typically a ground lead) | | **Lead Plating** | Silver-plated copper | --- ### 3. Detailed Breakdown of the Part Number The alphanumeric string provides specific details about the construction and size: * **S02**: Indicates the product series (High-temperature, immersion-resistant). * **07**: Refers to the size code (diameter of the sleeve). * **R**: Indicates the presence of a pre-installed lead/ground wire. * **98**: Specifically identifies the type of ground lead (e.g., specific gauge and plating). * **CS816**: A customer-specific or internal modification code used by TE Connectivity to track packaging or minor variations. --- ### 4. Key Functions and Applications 1. **EMI Shielding**: Connects the shield of a cable to a ground wire to prevent signal interference. 2. **Environmental Sealing**: The thermoplastic rings melt during installation to seal the connection against moisture and corrosion. 3. **Strain Relief**: The heat-shrink tubing provides mechanical strength, preventing the wire from snapping at the solder joint. 4. **Inspection**: The transparent sleeve allows for 100% visual inspection of the solder flow and the integrity of the connection. ### 5. Installation Process The part is installed using a **Heat Gun** with a specialized reflector: 1. The sleeve is placed over the stripped cable shield and ground lead. 2. Heat is applied, causing the sleeve to shrink. 3. The solder preform melts and flows into the shield strands. 4. The colored sealing rings melt to encapsulate the joint. ---
