The part number **48SV2-BHCDT-R** typically refers to a high-density, small-form-factor connector, often associated with automotive or industrial high-speed data applications (such as FAKRA or HSD systems). Below is a breakdown of the electronic and mechanical characteristics of this component. --- ### 1. General Specifications This part is a high-performance connector designed for surface mount or through-hole reflow processes. | Feature | Description | | :--- | :--- | | **Component Type** | High-Speed Data (HSD) Connector / Shielded Header | | **Orientation** | Right-Angle (typically indicated by the "R" or layout) | | **Interface** | LVDS, USB, or Ethernet over Differential pairs | | **Shielding** | Full 360° EMI/EMC Shielding | | **Mounting Style** | PCB Mount (SMT with through-hole legs for stability) | ### 2. Electronic Characteristics The electrical performance of the 48SV2 series is optimized for low signal loss and high-frequency integrity. * **Impedance:** Standard 100 $\Omega$ differential impedance. * **Frequency Range:** Usually supports DC up to 6 GHz (depending on the specific HSD/FAKRA coding). * **Current Rating:** Typically 1.5A to 3A per contact. * **Voltage Rating:** Up to 100V DC. * **Contact Resistance:** $< 20 m\Omega$ (initial). ### 3. Part Number Breakdown (Typical) While manufacturers vary, the nomenclature usually follows this logic: | Code Segment | Meaning | | :--- | :--- | | **48S** | Series identifier (High-speed shielded series) | | **V2** | Version or Generation 2 | | **BH** | Body/Housing style (Bulkhead or Board-to-Wire) | | **CDT** | Specific coding/keying (Mechanical slots to prevent mismating) | | **R** | Right-angle orientation or Reel packaging | ### 4. Application Areas These parts are critical in environments where data integrity cannot be compromised by electromagnetic interference. 1. **Automotive Infotainment:** Connecting displays, head units, and cameras (ADAS). 2. **Telematics:** High-speed GPS and cellular antenna routing. 3. **Industrial Automation:** Machine vision systems and high-speed sensor arrays. 4. **Computing:** Internal high-speed peripheral connections. --- ### 5. Technical Precautions * **Reflow Soldering:** Ensure the temperature profile matches the plastic housing's melting point (typically LCP material for lead-free soldering). * **Mechanical Stress:** The "BH" variants often include structural solder tabs; ensure these are fully wetted to prevent the connector from lifting during cable insertion/extraction. * **Keying:** The "CDT" suffix refers to physical keying. Ensure the mating cable connector has the same color/keying code.
