The **M2AS1-5233-R2/N** is a specific electronic component, typically categorized as a **Micro-USB Connector** or a high-precision **SMT (Surface Mount Technology) connector** used in telecommunications and mobile devices. Below is a breakdown of its electronic characteristics and technical specifications. --- ### 1. Technical Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Micro-USB Type B / Interface Connector | | **Mounting Type** | SMT (Surface Mount) with Shell DIP (Through-hole legs) | | **Contact Material** | Copper Alloy (typically Gold-plated for conductivity) | | **Current Rating** | 1.0A - 1.8A (depending on VCC pins) | | **Voltage Rating** | 30V AC/DC | | **Insulation Resistance** | 100M $\Omega$ Min | | **Operating Temp** | -30°C to +85°C | --- ### 2. Key Physical Parts and Construction #### A. Housing (Insulator) The internal structure is usually made of **LCP (Liquid Crystal Polymer)** or high-temperature Nylon. This material is chosen for its ability to withstand infrared (IR) reflow soldering temperatures without melting or deforming. #### B. Contact Terminals (Pins) * **Signal Pins:** Responsible for data transmission (D+ and D-). * **Power Pins:** VBUS and Ground. * **ID Pin:** Used for OTG (On-The-Go) detection. * **Plating:** Usually features selective gold plating on the contact area to prevent oxidation and ensure low contact resistance over thousands of cycles. #### C. Metallic Shell (Shielding) The "R2/N" suffix often refers to the specific mechanical design of the outer shell. * **EMI Shielding:** Protects the signal from electromagnetic interference. * **Structural Integrity:** Features "legs" or "tabs" that are soldered into the PCB to provide mechanical strength, preventing the connector from being ripped off the board during cable insertion. --- ### 3. Application and Usage This part is commonly found in: 1. **Mobile Handsets:** Charging ports for older smartphones or budget devices. 2. **IoT Modules:** Power supply and firmware flashing interfaces for microcontrollers. 3. **Portable Electronics:** Bluetooth speakers, power banks, and GPS units. --- ### 4. PCB Footprint Details * **Pitch:** Standard 0.65mm pitch for the 5-pin configuration. * **Orientation:** Right-angle, Top-mount. * **R2/N Variation:** Often indicates a specific "Reversed" type or a specific height requirement relative to the PCB plane.
