The **JFX1-4WE-R** is a specific electronic component typically categorized as a high-density, high-performance **board-to-board connector** or a **cable assembly connector**, often manufactured by companies like **Hirose Electric**. Below is a detailed breakdown of its specifications, architecture, and common applications. --- ### 1. General Specifications The "JFX" series is designed for high-speed differential signal transmission and space-saving on PCBs. | Feature | Specification | | :--- | :--- | | **Series** | JFX Series | | **Connector Type** | Board-to-Board / High-speed | | **Number of Contacts** | 4 (based on "4WE" designation) | | **Mounting Type** | Surface Mount (SMT) or Cable-end | | **Termination** | Solder / Crimp (depending on specific sub-type) | | **RoHS Compliant** | Yes | --- ### 2. Key Technical Features * **High-Speed Signal Integrity:** Designed to minimize crosstalk and impedance mismatch, making it suitable for protocols like USB 3.0, PCIe, or high-definition video data. * **Compact Footprint:** Engineered for low-profile electronic devices where vertical or horizontal space is limited. * **Wiping Contact Design:** Ensures a reliable electrical connection by "wiping" away surface contaminants during the mating process. * **Secure Locking:** Often features a mechanical lock or a friction-fit mechanism to prevent accidental disconnection due to vibration. --- ### 3. Pinout and Internal Structure The "4WE" suffix usually indicates the pin configuration. In standard JFX terminology: 1. **Housing:** Made of high-temperature thermoplastic (LCP - Liquid Crystal Polymer) to withstand reflow soldering. 2. **Contacts:** Copper alloy with gold plating to ensure high conductivity and prevent oxidation. 3. **Shielding:** Some versions include a metal shell for EMI (Electromagnetic Interference) protection. --- ### 4. Typical Applications This part is commonly found in modular electronics where high-frequency data must pass between two circuit boards: * **Consumer Electronics:** Smartwatches, cameras, and handheld gaming consoles. * **Industrial:** Interface modules for sensors or PLCs. * **Automotive:** Infotainment systems and ADAS (Advanced Driver Assistance Systems) sensor links. * **Medical:** Portable diagnostic equipment. --- ### 5.
