The **WJFT5-U2BA-R** is a specific electronic component, typically categorized as a high-speed data connector, most commonly used in telecommunications and networking hardware. Below is a detailed breakdown of its specifications and design. ### 1. General Overview The WJFT5 series is part of the **SFP (Small Form-factor Pluggable)** family. Specifically, this part number refers to an **SFP+ 1x1 Cage and Connector assembly** designed for high-speed data transmission. --- ### 2. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | SFP+ (Enhanced Small Form-factor Pluggable) | | **Port Configuration** | 1x1 (Single Port) | | **Mounting Type** | Through-Hole (Press-fit or Solder) | | **Orientation** | Right Angle / Horizontal | | **Shielding** | Integrated Metal Cage (EMI Shielding) | | **Data Rate** | Typically supports up to 10 Gbps | | **Standard Compliance** | SFF-8431 / SFF-8432 | --- ### 3. Key Electronic Features #### A. EMI Shielding (Electromagnetic Interference) The "Cage" aspect of this part is crucial. It acts as a Faraday cage to prevent electromagnetic interference from leaking out of the high-speed transceiver or affecting nearby sensitive components on the PCB. #### B. Heat Dissipation The metal housing is designed with thermal management in mind, often featuring venting holes or compatibility with clip-on heat sinks to manage the heat generated by the optical or copper transceiver modules. #### C. Signal Integrity The internal connector pins are gold-plated to ensure low contact resistance and high durability (mating cycles). The layout is optimized to maintain impedance control, which is vital for 10Gbps+ signaling. --- ### 4. Applications This part is commonly found in the following hardware: * **Network Switches & Routers:** For fiber optic or copper uplinks. * **Network Interface Cards (NICs):** High-speed server connectivity. * **Storage Area Networks (SAN):** Used in high-speed data storage arrays. * **Telecommunication Infrastructure:** Base stations and data center equipment. --- ### 5. Identification (Part Number Breakdown) While naming conventions vary by manufacturer (often associated with brands like **UDE** or similar high-speed connector specialists), the suffix usually denotes: * **U2:** Specific series/revision. * **BA:** Contact plating or housing material variations. * **R:** Usually indicates **RoHS Compliance** or **Tape & Reel** packaging.
