The **MH17FCD-R** is a specific technical component, typically identified as a **Micro-USB Connector** (Type B, Female). These parts are widely used in consumer electronics for power delivery and data transfer. --- ### 1. General Specifications Below are the typical electronic characteristics for a connector of this class: | Feature | Specification | | :--- | :--- | | **Connector Type** | Micro USB Type B (Female/Receptacle) | | **Mounting Type** | Surface Mount (SMD) / Through-hole Shield Tabs | | **Number of Pins** | 5 Pins (VCC, D-, D+, ID, GND) | | **Current Rating** | 1.0A - 1.8A per contact | | **Voltage Rating** | 30V AC/DC | | **Durability** | ~10,000 Mating Cycles | --- ### 2. Physical Construction The "MH17FCD-R" designation usually refers to the physical footprint and material composition: * **Housing:** High-temperature thermoplastic (LCP or Nylon), designed to withstand reflow soldering temperatures. * **Contacts:** Copper alloy with selective gold plating (to prevent oxidation and ensure low contact resistance). * **Shell:** Stainless steel or copper alloy with nickel plating, providing structural integrity and EMI shielding. * **Lead Configuration:** Usually features "Gull-wing" leads for the signal pins and structural tabs (legs) that are soldered into the PCB for mechanical strength. --- ### 3. Pinout Configuration The 5-pin layout is standard for Micro-USB parts: 1. **Pin 1 (VCC):** +5V Power. 2. **Pin 2 (D-):** Data Minus. 3. **Pin 3 (D+):** Data Plus. 4. **Pin 4 (ID):** Permits distinction between Host and Slave (OTG). 5. **Pin 5 (GND):** Ground. --- ### 4. Common Applications Due to its compact size and high durability, this part is found in: * **Mobile Accessories:** Power banks, Bluetooth speakers, and headphones. * **Development Boards:** Small microcontrollers (similar to older Arduino Pro Micro or ESP8266 boards). * **IoT Devices:** Smart home sensors and handheld controllers. ---
