The part number **WRPPB-M7K7AR-R** typically refers to a high-density, board-to-board connector assembly, often used in telecommunications, servers, and high-speed computing environments. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This component is designed for high-signal integrity and robust mechanical stability. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Board-to-Board Connector | | **Pitch** | 0.7mm to 0.8mm (Part specific) | | **Pin Configuration** | Multi-row / High Density | | **Mounting Type** | Surface Mount (SMD) | | **Contact Material** | Copper Alloy with Gold Plating | | **RoHS Status** | Compliant (-R suffix often indicates RoHS) | --- ### 2. Technical Breakdown The nomenclature usually follows a specific manufacturer's coding (common in the industry for mezzanine-style connectors): * **WRPPB Series**: Refers to the product family, typically a Plug or Receptacle used for mezzanine stacking. * **M7/K7**: These characters often define the **Pin Count** and **Stack Height**. In these series, "M7" or "K7" frequently correlates to specific mechanical heights (e.g., 7mm) to ensure the gap between two PCBs is precise. * **AR**: Indicates the plating and material specification (e.g., Gold flash or selective gold plating to prevent oxidation). * **-R**: Generally indicates **Tape and Reel** packaging for automated pick-and-place assembly. --- ### 3. Key Electronic Characteristics These connectors are engineered for high-performance data transmission. * **Current Rating**: Usually 0.5A to 1.0A per pin. * **Voltage Rating**: Typically 50V to 100V AC/DC. * **Impedance Matching**: Designed to maintain 50Ω or 100Ω differential impedance for high-speed signals (PCIe, Ethernet, etc.). * **Durability**: Rated for approximately 30 to 50 mating cycles. --- ### 4. Typical Applications These parts are found in modular electronic systems where space is at a premium: 1. **Blade Servers**: Connecting CPU boards to backplanes. 2. **Network Switches**: Interconnecting logic boards and I/O modules. 3. **Industrial Automation**: Connecting PLC modules. 4. **Medical Equipment**: High-density signal routing in imaging devices. ---
