The **FJFT4-U36-R** is a high-performance **USB 3.1 Type-C female connector** designed for surface mount technology (SMT) applications. It is commonly used in modern electronics requiring high-speed data transfer and power delivery in a compact form factor. --- ### ## Technical Specifications Below are the primary electronic and mechanical characteristics of the FJFT4-U36-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | USB Type-C (Female/Receptacle) | | **Standard** | USB 3.1 Gen 2 | | **Data Transfer Rate** | Up to 10 Gbps | | **Current Rating** | 3A to 5A (Power Delivery Support) | | **Mounting Type** | SMT (Surface Mount) + Through-hole Shell Tabs | | **Number of Pins** | 24 Pins | | **Contact Resistance** | 40 mΩ Max | | **Insulation Resistance** | 100 MΩ Min | --- ### ## Key Electronic Components & Design #### 1. Pin Configuration (24-Pin Layout) The connector utilizes a standard 24-pin symmetrical layout, allowing for **reversible insertion**. * **VBUS & GND:** Dedicated pins for power transmission, supporting up to 100W in specific PD (Power Delivery) configurations. * **TX/RX Differential Pairs:** Two sets of high-speed lanes for USB 3.1 10Gbps data throughput. * **CC1/CC2 (Configuration Channel):** Used for cable orientation detection and power negotiation. * **D+/D-:** Legacy support for USB 2.0 data speeds. #### 2. Structural Integrity * **Shielding:** The outer shell is typically made of stainless steel or copper alloy with nickel plating to provide EMI/RFI protection and mechanical grounding. * **Housing:** High-temperature thermoplastic (LCP) capable of withstanding reflow soldering temperatures. #### 3. Hybrid Mounting The "FJFT" series often features a **hybrid mount** design. This means the signal pins are surface-mounted (SMT) for high-density routing, while the structural "legs" or shell tabs are through-hole (DIP) to provide superior mechanical strength against frequent plugging/unplugging. --- ### ## Common Applications * **Consumer Electronics:** Smartphones, tablets, and laptops. * **Peripherals:** External SSD enclosures and high-speed docking stations. * **Industrial:** Embedded systems requiring rugged, high-speed interfaces. * **Charging:** Fast-charging wall adapters and power banks.
