The part number **47DM-1026-R/Q** typically refers to a specialized **Automotive-Grade Micro-USB or Interface Connector**, often associated with manufacturers like **Hosiden** or similar automotive component suppliers. Below is a breakdown of its technical characteristics and role in electronic systems. --- ### 1. General Specifications The "47DM" series is designed to meet high-reliability standards required for in-vehicle infotainment and telematics. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Micro-USB Type B / Interface Connector | | **Mounting Type** | Surface Mount (SMT) / Through-hole hybrid | | **Orientation** | Right Angle | | **Pin Count** | 5-Pin (Standard USB) or customized multi-pin | | **Automotive Grade** | AEC-Q100/200 compliant (implied by "Q" suffix) | | **Shielding** | Full Metal Shield for EMI/EMC protection | --- ### 2. Suffix Breakdown * **-R**: Generally indicates **RoHS Compliance** (Restriction of Hazardous Substances), ensuring the part is lead-free. * **-Q**: Often denotes **Automotive Quality** or "Quality Assurance" testing, indicating the part can withstand higher vibration, shock, and temperature fluctuations (-40°C to +85°C or higher). --- ### 3. Key Electronic Characteristics * **Contact Resistance:** Typically low (under 30mΩ) to prevent signal loss. * **Durability:** High mating cycle rating (often 5,000 to 10,000 cycles) to handle frequent plugging/unplugging by users. * **Current Rating:** Standard 1.0A to 1.8A per pin (for charging capabilities). * **Voltage Rating:** 30V AC/DC. --- ### 4. Applications This part is predominantly found in the following electronic modules: 1. **Car Head Units:** For connecting smartphones to Apple CarPlay or Android Auto. 2. **Navigation Systems:** Data transfer and firmware updates. 3. **Dash Cams / Sensors:** Power and data interface for internal vehicle recording. 4. **Diagnostic Tools:** Interface ports for OBD-II related handheld devices. --- ### 5. Footprint and Mechanical Design The physical structure usually includes **metal tabs (legs)** that are soldered into the PCB. These provide mechanical "pegs" so that if a user pulls on the cable, the solder joints of the signal pins do not snap off. ```text Visual Representation (Top View): [ Shielded Metal Housing ] | ( ) ( ) ( ) ( ) ( ) | <-- Data/Power Pins |____________________________| |__| |__| <-- Solder Reinforcement Tabs ```
