The **ADY-142-R** is a specific electronic component typically categorized as a **Micro-USB Connector**. It is designed for Surface Mount Technology (SMT) applications, commonly found in mobile devices, charging ports, and data transfer interfaces. --- ### 1. Technical Specifications The following table highlights the core electrical and mechanical characteristics of the ADY-142-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Micro-USB Type B Receptacle | | **Orientation** | Horizontal (Right Angle) | | **Mounting Type** | SMT (Surface Mount) with Shell Tabs | | **Current Rating** | 1.0A to 1.8A (Pin dependent) | | **Voltage Rating** | 30V AC/DC | | **Durability** | ~10,000 Mating Cycles | | **Material (Shell)** | Stainless Steel or Copper Alloy (Nickel Plated) | | **Pin Configuration** | 5-Pin (VCC, D-, D+, ID, GND) | --- ### 2. Key Design Features * **Physical Form Factor:** It is a "B-type" micro-USB, which is the standard trapezoidal shape used for non-Apple smartphones and peripherals before the widespread adoption of USB-C. * **Mechanical Stability:** The "-R" variant often denotes specific packaging (like Tape & Reel) or a reinforced shell design. It usually features "solder tabs" that go through the PCB or sit on pads to provide mechanical strength against cable pulling. * **Lead-Free Compliance:** These parts are generally RoHS compliant, meaning they are manufactured without hazardous materials like lead or cadmium. --- ### 3. Common Applications The ADY-142-R is utilized in various consumer electronics including: 1. **Mobile Accessories:** Power banks, Bluetooth speakers, and wireless headphones. 2. **Development Boards:** Often found on older versions of Arduino or ESP8266/ESP32 modules for programming and power. 3. **Industrial Devices:** Handheld scanners or data loggers requiring a compact data interface. --- ### 4. Footprint and Soldering When designing a PCB for this part, the footprint typically requires: * **Five Signal Pads:** For the electrical connections (pitch is usually 0.65mm). * **Four Structural Pads:** Large pads on the sides to solder the metal shield to the board’s ground plane for EMI shielding and physical durability. ```markdown Pinout Diagram (Top View): [ 1 2 3 4 5 ] | | | | |_ Ground (GND) | | | |____ ID (Identification) | | |_______ Data + (D+) | |__________ Data - (D-) |_____________ VCC (+5V) ```
