The **47DM-1014-R** is a specific electronic component, typically categorized as a **Micro-SD Card Connector** or a **Memory Card Slot**. These parts are designed to provide a secure mechanical and electrical interface between a Micro-SD storage card and a Printed Circuit Board (PCB). --- ### 1. Key Technical Specifications Below is a breakdown of the typical characteristics for this specific part number: | Feature | Specification | | :--- | :--- | | **Component Type** | Micro-SD Card Connector | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Card Ejection Mechanism** | Push-Push (Push to insert, Push to eject) | | **Number of Pins** | 8 Main Pins + Ground/Shield Pins | | **Orientation** | Right Angle / Top Entry | | **Material** | High-temperature Thermoplastic / Copper Alloy Contacts | | **Plating** | Gold over Nickel (on contact areas) | --- ### 2. Functional Anatomy The 47DM-1014-R consists of several critical sub-components that ensure data integrity and physical durability: * **Housing:** Usually made of LCP (Liquid Crystal Polymer) to withstand the high heat of reflow soldering. * **Contacts:** Precision-stamped metal pins that press against the Micro-SD card's pads. Gold plating is used to prevent oxidation and ensure low contact resistance. * **Shell/Shield:** A stainless steel outer shell that provides Structural rigidity and EMI (Electromagnetic Interference) shielding. * **Card Detection Switch:** An integrated mechanical switch that signals the microcontroller (MCU) when a card is physically present in the slot. --- ### 3. Common Applications This part is commonly found in compact electronic devices that require expandable storage: 1. **IoT Devices:** Security cameras, sensors, and data loggers. 2. **Consumer Electronics:** MP3 players, handheld gaming consoles, and GPS units. 3. **Industrial Computing:** Embedded systems that require OS booting from a removable flash card. 4. **Development Boards:** Often used on custom PCB shields for Arduino or Raspberry Pi-based projects. --- ### 4. Footprint and Soldering Considerations * **SMT Leads:** The "R" in the suffix often indicates "Reel" packaging for automated pick-and-place machines. * **Soldering:** Because it is an SMT part, it requires a solder paste stencil and a reflow oven profile that matches the plastic's thermal rating. * **Mechanical Strength:** It often features "solder tabs" on the sides of the metal shell to provide extra mechanical strength, preventing the connector from being ripped off the board during repeated card insertions.
