The **U36-R** is a specific type of **USB Type-C (USB-C) connector**, widely used in electronics for Surface Mount Technology (SMT). It is commonly found in charging ports for smartphones, tablets, and high-performance peripherals. Below is a breakdown of the electronic components and technical specifications related to the U36-R series. --- ### 1. Technical Specifications The U36-R is defined by its compact footprint and high-speed data transmission capabilities. | Feature | Description | | :--- | :--- | | **Connector Type** | USB Type-C 3.1 / 3.2 | | **Mounting Type** | SMT (Surface Mount Technology) / Mid-Mount | | **Pin Count** | 24 Pins (Standard Full-Featured) | | **Current Rating** | 3A to 5A (Support for Power Delivery) | | **Voltage Rating** | 20V DC | | **Durability** | 10,000 Mating Cycles | --- ### 2. Key Electronic Parts & Structure The U36-R is not just a piece of metal; it consists of several critical layers and materials: #### A. Housing and Insulator * **Material:** High-temperature thermoplastic (usually LCP - Liquid Crystal Polymer). * **Function:** Ensures the 24 pins do not short-circuit and provides structural integrity during the soldering process. #### B. Contact Pins (The "Guts") * **Material:** Copper Alloy (Brass or Phosphor Bronze). * **Plating:** Usually **Gold plating** on the contact area to prevent oxidation and ensure low resistance, with Nickel underplating. * **Configuration:** Includes VBUS (Power), GND (Ground), CC1/CC2 (Configuration Channels), and Differential Pairs (D+/D- for USB 2.0 and TX/RX for USB 3.0+). #### C. Outer Shell (Shielding) * **Material:** Stainless Steel or Nickel-plated Steel. * **Function:** Provides EMI (Electromagnetic Interference) shielding and mechanical grounding to the PCB via "legs" or tabs. --- ### 3. Pinout Functionality The U36-R utilizes the standard 24-pin USB-C layout, divided into two rows (A and B): 1. **VBUS/GND:** Power supply pins. 2. **CC1/CC2:** Used for cable orientation detection and **Power Delivery (PD)** negotiation. 3. **D+/D-:** Legacy USB 2.0 data transfer. 4. **TX/RX Pairs:** High-speed data lanes for USB 3.1/4.0 or Alt-modes (DisplayPort). --- ### 4. Implementation Example If you were to design a PCB using the U36-R, your schematic would look like this: ```cpp // Typical Pin Assignment for a U36-R Interface Pin 1, 12, 13, 24 -> GND (System Ground) Pin 4, 9, 16, 21 -> VBUS (Power Input, 5V-20V) Pin A5 -> CC1 (Configuration Channel 1) Pin B5 -> CC2 (Configuration Channel 2) Pin A6/A7 -> D+/D- (USB 2.0 Data) ``` ---
