The part number **48NDR-0RA-R** typically refers to a high-density, small-form-factor **Multi-Gigabit connector** or a specific **I/O interconnect** assembly, often associated with manufacturers like Foxconn or specialized electronic component distributors. Below is a detailed breakdown of the technical specifications, features, and applications for this type of component. --- ### 1. Technical Specifications | Parameter | Description | | :--- | :--- | | **Component Type** | High-speed I/O Connector / Socket | | **Interface** | Often associated with SAS, PCIe, or custom high-speed data buses | | **Mounting Type** | Surface Mount (SMT) or Press-fit (depending on specific revision) | | **Orientation** | Right-Angle (indicated by the 'RA' in the suffix) | | **Data Rate** | Typically supports 12Gbps to 24Gbps per lane | | **Plating** | Gold over Nickel (standard for high-frequency signal integrity) | --- ### 2. Breakdown of the Part Suffix The alphanumeric code often follows a specific logic: * **48N**: Designates the series or pin count (in some series, this indicates 48 positions). * **DR**: Dual Row configuration. * **0RA**: Right Angle orientation (allows the cable or daughterboard to sit parallel to the main PCB). * **-R**: RoHS Compliant (Lead-free). --- ### 3. Key Features * **High Signal Integrity:** Designed with impedance matching to minimize crosstalk and signal loss at high frequencies. * **Compact Footprint:** Engineered for high-density server environments where PCB real estate is limited. * **Robust Shielding:** Often includes metal EMI (Electromagnetic Interference) shielding to prevent noise leakage. * **Heat Resistance:** Built using high-temperature LCP (Liquid Crystal Polymer) plastic to withstand reflow soldering processes. --- ### 4. Common Applications These parts are primarily found in the infrastructure layer of computing: 1. **Data Centers:** Used in server backplanes and storage arrays. 2. **Networking Hardware:** High-speed switches and routers. 3. **Industrial Computing:** Embedded systems requiring reliable, high-speed data transfer between boards. 4. **Storage Systems:** Interfacing SSD arrays using SAS (Serial Attached SCSI) protocols. --- ### 5.
