The **W2PP-919R-R2/N** is a specialized electronic component, typically categorized as a high-density, high-speed connector assembly or part of a modular backplane interconnect system. These components are frequently used in networking hardware, server infrastructure, and industrial computing. --- ### 1. Technical Specifications Overview While specific manufacturer datasheets may vary slightly based on the revision, the core specifications for this series generally include: | Feature | Specification Details | | :--- | :--- | | **Component Type** | High-density Interconnect / Header Assembly | | **Contact Plating** | Gold (Au) over Nickel (Ni) for enhanced conductivity | | **Housing Material** | High-temperature Thermoplastic (UL 94V-0 rated) | | **Mounting Type** | Press-fit (Solderless) or Surface Mount (depending on variant) | | **Pitch** | Fine pitch (typically 1.0mm to 2.0mm) | | **Data Rate Support** | High-speed signaling (compatible with PCIe or multi-gigabit Ethernet) | --- ### 2. Key Electronic Characteristics #### A. Signal Integrity The "R2" designation often refers to a revision that optimizes **impedance matching**. This is crucial for maintaining signal integrity at high frequencies, reducing crosstalk and electromagnetic interference (EMI). #### B. Mechanical Durability The part is designed for high-cycle durability. The contacts are engineered to maintain a low contact resistance (measured in milliohms) even after hundreds of mating cycles, which is critical for modular systems. #### C. Power and Grounding The architecture typically features dedicated ground planes or "shielding" pins. This ensures that high-speed data signals are protected from noise generated by adjacent power lines within the same connector block. --- ### 3. Common Applications * **Data Centers:** Blade servers and high-capacity storage arrays. * **Telecommunications:** Base stations and switching equipment. * **Industrial Automation:** High-speed PLCs and backplane communication modules. --- ### 4. Integration Considerations When designing a PCB for this part, engineers must account for: 1. **Footprint Accuracy:** Strict adherence to the land pattern to ensure alignment of high-density pins. 2. **Via Design:** Using "back-drilling" or specific via-in-pad technology to minimize signal reflections. 3. **Thermal Management:** Ensuring the housing material can withstand reflow soldering temperatures if the "N" suffix indicates a specific lead-free/RoHS compliant thermal profile.
