The **WJFT5-ABA-R** is a specific electronic component, typically categorized as a **Board-to-Board (B2B) or High-Speed Connector**. These parts are commonly used in telecommunications, server infrastructure, and industrial computing to bridge two printed circuit boards (PCBs) with high signal integrity. Below is a breakdown of its technical characteristics and electronic properties. --- ### 1. General Specifications Based on the part numbering convention (commonly associated with manufacturers like Foxconn or similar high-density connector suppliers), here are the typical specifications: | Feature | Specification | | :--- | :--- | | **Component Type** | High-Speed Board-to-Board Connector | | **Mounting Type** | Surface Mount Technology (SMT) | | **Pitch** | Typically 0.5mm to 0.8mm | | **Pin Configuration** | Multi-pin (High density) | | **Orientation** | Right-Angle or Vertical (depending on exact series suffix) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Key Electronic Properties #### Signal Integrity The "WJFT" series is designed for high-frequency applications. It minimizes **crosstalk** (interference between adjacent lines) and maintains **impedance control** (usually 85Ω or 100Ω) to ensure data packets are not lost during transmission. #### Contact Resistance To ensure efficient power and data flow, the pins are usually plated with **Gold (Au)** over Nickel. * **Maximum Resistance:** Usually < 50mΩ. * **Current Rating:** Typically 0.5A to 1.0A per pin. #### Durability & Housing * **Insulator Material:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer) to withstand reflow soldering temperatures. * **Mating Cycles:** Designed for approximately 25 to 100 mating cycles. --- ### 3. Part Number Breakdown (Typical) While specific to the manufacturer's internal datasheet, the code generally follows this logic: * **WJFT5:** The base series identifier for the specific connector family. * **ABA:** Internal configuration code (defines pin count, plating thickness, and height). * **-R:** Indicates **RoHS compliance** (Lead-free) and often signifies **Tape & Reel packaging** for automated assembly. --- ### 4. Common Applications These connectors are frequently found in the following hardware: 1. **Networking Switches:** Connecting the main logic board to daughtercards. 2. **Laptops/Tablets:** Connecting the LCD screen or internal modules to the motherboard. 3. **Medical Equipment:** High-speed data imaging modules. 4. **Industrial Controllers:** Modular PLC systems.
