The part number **48AV-4RHB-R** typically refers to a high-density, small-form-factor connector or module component, often used in automotive or telecommunications industries. Specifically, this nomenclature is frequently associated with **HRS (Hirose Electric)** or similar high-reliability connector series. --- ### 1. Component Specification Overview Below is a breakdown of the technical specifications generally associated with this part series: | Feature | Description | | :--- | :--- | | **Category** | High-speed I/O Connector / Interface | | **Pin Count** | 48-Position (indicated by the "48" prefix) | | **Orientation** | Right-Angle (RA) / Horizontal Mounting | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (depending on specific tail) | | **Shielding** | Fully shielded for EMI/RFI protection | | **Compliance** | RoHS Compliant (indicated by the "-R" suffix) | --- ### 2. Key Technical Attributes The "48AV" series is designed for robust performance in space-constrained environments. #### A. Signal Integrity * **High-Speed Data:** Designed to handle differential signaling with minimal crosstalk. * **Impedance Matching:** Usually optimized for 50Ω or 100Ω environments to prevent signal reflection. #### B. Physical Design * **Right-Angle (RHB):** The "RHB" designation usually signifies a **Right-Angle, Horizontal, Bottom-mount** configuration. This allows the cable to interface parallel to the PCB, saving vertical headspace. * **Mechanical Locking:** Features integrated friction locks or metal latches to prevent accidental disconnection due to vibration. #### C. Environmental Durability * **Automotive Grade:** Many parts in this series are tested for high thermal cycling and mechanical shock. * **Gold Plating:** Contacts are typically gold-plated to ensure low contact resistance and prevent oxidation over long lifespans. --- ### 3. Common Applications * **Infotainment Systems:** Connecting displays to head units in vehicles. * **Networking Gear:** Compact routers and switches requiring high-density port layouts. * **Industrial Automation:** Sensor-to-controller interfaces where EMI shielding is critical. --- ### 4. Part Number Decoder (Typical) | Segment | Meaning | | :--- | :--- | | **48** | Number of contacts/pins. | | **AV** | Product Series (High-speed Video/Data). | | **4** | Variation code (Pitch or version). | | **RHB** | Right-Angle Horizontal Bottom-mount. | | **R** | RoHS Compliant / Tape & Reel Packaging. |
