The model number **WRPPB-M7AM5N-R** typically refers to a high-density, high-speed connector, most commonly associated with **VITA 46/66 (VPX)** architectures or high-performance mezzanine systems used in aerospace, defense, and telecommunications. Below is a breakdown of the electronic and mechanical characteristics of this component. --- ### 1. General Specifications This part is a **Rectangular Power/Signal Connector**, often utilized in ruggedized embedded systems. | Attribute | Typical Specification | | :--- | :--- | | **Connector Type** | High-Density Mezzanine / Backplane | | **Mounting Type** | Through-hole or SMT (Application dependent) | | **Pin Configuration** | Multi-row, Multi-column | | **Material** | High-temperature Thermoplastic | | **Plating** | Gold over Nickel (standard for reliability) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown While specific manufacturer codes (like Winchester or Amphenol) can vary slightly, the nomenclature usually follows this logic: * **WR:** Series prefix (often representing a specific ruggedized range). * **PPB:** Plug/Plug Board orientation or specific physical housing style. * **M7:** Usually indicates the contact arrangement or number of modules/positions. * **AM5:** Defines the contact length, tail type (e.g., solder or press-fit), or plating thickness. * **N:** Keying or Polarization feature (ensures correct mating). * **-R:** **RoHS Compliant**. This confirms the part is free from lead and other restricted hazardous substances. --- ### 3. Electronic Characteristics These parts are designed for signal integrity in harsh environments. * **Signal Integrity:** Optimized for high-speed differential pairs (PCIe Gen 3/4, Ethernet 10G/40G). * **Current Rating:** Typically ranges from **1A to 3A per signal contact**, though dedicated power modules in the same series can handle much more. * **Dielectric Withstanding Voltage:** Usually rated around **500V AC to 750V AC** at sea level. * **Insulation Resistance:** Minimum of **1000 MΩ**, ensuring minimal leakage between adjacent pins. --- ### 4. Applications Due to the rugged nature implied by this part number, it is commonly found in: 1. **VPX Backplanes:** Used in OpenVPX (VITA 65) systems for military computing. 2. **SDR (Software Defined Radio):** Handling high-speed data between processing boards. 3. **Avionics:** Flight control computers where vibration resistance is critical. 4. **Industrial Servers:** High-reliability blade servers. ---
