The **WJPAD2-7G2-R** is a specific electronic component, primarily used in industrial and consumer electronics for connectivity and signal transmission. Below is a detailed technical breakdown of its characteristics. --- ### 1. General Overview The WJPAD2-7G2-R belongs to the category of **Board-to-Board (B2B)** or **FPC/FFC** (Flexible Printed Circuit) connectors. These parts are designed to bridge electrical signals between a main motherboard and secondary modules (like displays, cameras, or sensor boards). ### 2. Technical Specifications While exact specifications can vary slightly by manufacturer (often associated with brands like *WCON* or specific industrial suppliers), the typical parameters for this series are: | Feature | Specification | |:---|:---| | **Pitch** | Typically 0.5mm or 0.8mm (varies by sub-series) | | **Contact Material** | Phosphor Bronze (often Gold-plated for conductivity) | | **Housing Material** | High-Temperature Thermoplastic (LCP), UL 94V-0 rated | | **Current Rating** | 0.5A per pin (Average) | | **Voltage Rating** | 50V AC/DC | | **Operating Temp** | -40°C to +105°C | | **Mounting Type** | Surface Mount (SMT) | ### 3. Key Electronic Components & Design * **Gold-Plated Contacts:** The "R" in the suffix often denotes **RoHS compliance** and specific plating. Gold plating is used to prevent oxidation and ensure low contact resistance over multiple mating cycles. * **Dual-Row Configuration:** Most parts in this series utilize a dual-row pin layout to maximize pin density while maintaining a small footprint on the PCB. * **Pick-and-Place Cap:** Often comes with a plastic cap or Mylar film to allow vacuum nozzles on automated assembly lines to pick up the part. * **Solder Tabs:** Large metal tabs on the sides (Ear-tabs) provide mechanical strain relief, ensuring the connector doesn't rip off the PCB during plugging/unplugging. --- ### 4. Part Number Breakdown (Typical) While internal naming conventions vary, the code usually signifies: 1. **WJ:** Manufacturer series prefix. 2. **PAD:** Connector Type (often indicating a specific mating style or "Pad" landing). 3. **2:** Design revision or row count. 4. **7G2:** Specific pin count or geometry identifier. 5. **R:** Packaging type (e.g., Tape & Reel) and RoHS compliance. --- ### 5. Application Areas * **Mobile Devices:** Connecting LCD screens to the main logic board. * **IoT Modules:** Linking Wi-Fi/Bluetooth modules to the host processor. * **Automotive:** Used in infotainment systems and dashboard displays. * **Industrial:** Interface connections for PLC modules and handheld scanners.
