The **MH63FDD-R** is a specific electronic component primarily identified as a **Micro-USB Type B Receptacle**. It is a surface-mount device (SMD) used extensively in consumer electronics for power delivery and data transfer. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the MH63FDD-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | Micro USB Type B | | **Gender** | Receptacle (Female) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Number of Contacts** | 5 Pins | | **Current Rating** | Typically 1.0A - 1.8A | | **Voltage Rating** | 30V AC/DC | | **Orientation** | Right Angle / Horizontal | | **Shell Material** | Stainless Steel or Copper Alloy (Nickel Plated) | --- ### 2. Physical Layout and Pinout The MH63FDD-R features a standard 5-pin configuration essential for USB 2.0 communication: 1. **VBUS (+5V):** Power supply line. 2. **D-:** Data Negative. 3. **D+:** Data Positive. 4. **ID:** Identification (used for OTG - On-The-Go functions). 5. **GND:** Ground. --- ### 3. Structural Features * **Mechanical Durability:** Designed for high insertion cycles (typically rated for 10,000 cycles). * **Shielding:** The metal outer shell provides EMI/RFI protection and serves as a robust mechanical anchor to the PCB. * **Mounting Tabs:** Usually includes side "wings" or "tabs" that are soldered to the PCB pads to prevent the connector from being ripped off during cable insertion/removal. --- ### 4. Common Applications Due to its compact form factor, the MH63FDD-R is found in: * **Mobile Accessories:** Power banks, Bluetooth speakers, and headphones. * **Embedded Systems:** Development boards (similar to Arduino or ESP32 modules). * **Small Appliances:** Rechargeable flashlights, electric shavers, and IoT sensors. --- ### 5. Footprint Example (Generic) If you are designing a PCB, the footprint usually follows this logic: ```c // Schematic Symbol Logic [ VBUS ] -- Pin 1 [ D- ] -- Pin 2 [ D+ ] -- Pin 3 [ ID ] -- Pin 4 [ GND ] -- Pin 5 [SHELL ] -- Shield/Mechanical Ground ```
