Based on the part number **16646CSSC**, this component is a specialized high-current busbar connector, typically manufactured by companies like **Amphenol (specifically under the Radsert or SurLok Plus product lines)**. It is designed for high-power distribution applications. --- ### 1. Technical Specifications The "CSSC" suffix often indicates a specific configuration involving a **pressed-fit** or **solder-mount** interface for high-current PCB applications. | Feature | Description | | :--- | :--- | | **Component Type** | High-Current Power Connector / Busbar Terminal | | **Technology** | RADSOK® (Radial Socket) Technology | | **Current Rating** | Typically 35A to 70A (depending on board thickness and traces) | | **Mounting Style** | Press-fit or Surface Mount (Board-to-Board or Wire-to-Board) | | **Plating** | Silver or Tin (Standard for high conductivity) | | **Internal Diameter** | 2.4mm to 3.6mm (common for this series) | --- ### 2. Key Internal Technology: RADSOK® The core functionality of the 16646CSSC relies on **RADSOK®** technology. Unlike standard pin-and-socket connectors, this part features a hyperbolic grid inside the socket. * **High Contact Surface:** Provides more surface area contact than a standard cylinder. * **Low Insertion Force:** Allows for easy assembly without damaging the PCB. * **Low Resistance:** Minimizes voltage drop and heat generation at high amperages. --- ### 3. Common Applications These parts are rarely found in consumer electronics; they are primarily used in industrial and power-heavy environments: 1. **Data Centers:** Powering server blades and backplanes. 2. **Electric Vehicles (EV):** Battery Management Systems (BMS) and power inverters. 3. **Industrial Automation:** High-power motor controllers. 4. **Renewable Energy:** Solar inverters and energy storage systems. --- ### 4. Installation Example (Conceptual) When integrating this part into a design, engineers typically use a footprint similar to this in their CAD software: ```markdown # Footprint Requirements - Drill Diameter: 3.5mm (+/- 0.05mm) - Pad Diameter: 5.0mm - Solder Mask Clearance: 0.1mm - Current Path: Multiple internal 2oz copper layers recommended ```
