The **UT3PPG-AL6-R** is a specific electronic connector component, typically part of a high-density interconnect series. Below is a detailed breakdown of its specifications, construction, and typical applications. --- ### 1. Technical Specifications The UT3PPG-AL6-R is generally classified as a high-density, small-form-factor connector. While "UT3" often refers to the series lineage, the specific suffixes define its physical properties. | Feature | Description | | :--- | :--- | | **Series** | UT3 (Micro-connector / High-density) | | **Contact Plating** | Gold (Au) or Gold Flash (Indicated by 'G') | | **Mounting Type** | Right-Angle or Specific PCB Orientation | | **Material** | High-temperature Thermoplastic (UL94V-0) | | **Housing Color** | Typically Black or Natural | | **RoHS Status** | Compliant (Indicated by '-R') | --- ### 2. Key Component Breakdown #### A. Contact Material and Plating * **Gold Plating ('G'):** The use of gold on the contact surfaces ensures low contact resistance and prevents oxidation over time. This is critical for low-voltage signal integrity in consumer electronics. * **Base Metal:** Usually Phosphor Bronze, providing a balance of conductivity and mechanical spring tension. #### B. Mechanical Design * **Pitch:** These connectors usually feature a fine pitch (e.g., 0.5mm to 1.25mm), allowing for more connections in a smaller footprint. * **Locking Mechanism:** Often features a "friction lock" or a "positive lock" to ensure the cable remains seated under vibration. #### C. Environmental Compliance ('-R') * The **-R** suffix strictly denotes **RoHS (Restriction of Hazardous Substances) Compliance**, meaning it is free from lead, mercury, cadmium, and other restricted materials. --- ### 3. Common Applications Due to its small size and reliable gold-plated contacts, this part is commonly found in: 1. **Handheld Devices:** Smartphones, tablets, and handheld gaming consoles. 2. **Internal PCB Interconnects:** Connecting a secondary board (like a sensor board) to a main motherboard. 3. **Display Modules:** Connecting LCD/OLED screens to driving circuitry. 4. **Automotive Infotainment:** Compact signal routing for dashboards. --- ### 4. Part Number Decoder (Typical) | Code | Meaning | | :--- | :--- | | **UT3** | Series Identifier | | **PPG** | Plug / Gold Plated / Pitch configuration | | **AL6** | Specific pin count or physical dimension variant | | **R** | RoHS Compliant | ---
