The **MH44TCG-R** is a specific electronic component typically identified as a **Micro-USB Connector**. It is widely used in consumer electronics for power charging and data synchronization. --- ## 1. Component Overview The MH44TCG-R is a **Micro-USB Type B Female Receptacle**. It is designed for Surface Mount Technology (SMT) or Mid-Mount configurations on Printed Circuit Boards (PCBs). ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | Micro-USB Type B | | **Gender** | Female (Receptacle) | | **Orientation** | Right Angle / Horizontal | | **Mounting Type** | Surface Mount (SMT) / Mid-Mount | | **Number of Contacts** | 5 Pins | | **Rated Current** | 1.0A - 1.8A (depending on manufacturer) | | **Rated Voltage** | 30V AC/DC | --- ## 2. Pinout Configuration As a standard Micro-USB connector, the MH44TCG-R follows the universal 5-pin layout: 1. **VBUS (+5V):** Power supply. 2. **D- (Data Minus):** Differential data signal. 3. **D+ (Data Plus):** Differential data signal. 4. **ID:** Used to distinguish between Host and Peripheral (OTG). 5. **GND:** Ground. --- ## 3. Physical & Mechanical Features * **Shielding:** The outer shell is usually made of Stainless Steel or Copper Alloy with Nickel plating to prevent Electromagnetic Interference (EMI). * **Contacts:** Usually Gold-plated to ensure low contact resistance and high durability (rated for thousands of mating cycles). * **Housing:** High-temperature Thermoplastic (LCP or Nylon), allowing the part to withstand Reflow Soldering temperatures. --- ## 4. Common Applications * **Mobile Devices:** Smartphones, tablets, and e-readers. * **Charging Ports:** Power banks and battery-operated IoT devices. * **Peripherals:** Computer mice, keyboards, and wireless headphones. * **DIY Electronics:** Commonly used in ESP32 or Arduino-based projects for power and programming. ---
