The **MA16FBD-R** is a specific electronic component typically categorized as a **D-Sub Miniature Connector** (often used in industrial and telecommunications equipment). Below is a detailed breakdown of its electronic parts, specifications, and characteristics. --- ### 1. General Overview The MA series generally represents high-density or specialized D-sub connectors designed for reliable board-to-wire or board-to-board connections. | Feature | Description | | :--- | :--- | | **Component Type** | D-Sub Connector (Plug/Socket) | | **Pin Count** | 16 Pins (indicated by the "16" in the part number) | | **Gender** | Female (indicated by "F") | | **Mounting Style** | Right Angle (indicated by "R") | | **Termination** | Through-hole Solder | --- ### 2. Breakdown of the Part Number Understanding the nomenclature helps identify the physical and electrical properties: * **MA**: Series designation (Manufacturer specific, often related to Hirose or similar industrial standards). * **16**: Number of contact positions/pins. * **F**: Gender (Female/Socket). * **BD**: Specific shell or mounting hardware configuration (often refers to a "Board-lock" or specific mounting bracket). * **R**: Orientation (Right Angle), meaning the pins are bent 90 degrees to sit flat on a PCB. --- ### 3. Key Technical Specifications While exact specs can vary by manufacturer, these are the standard parameters for this class of connector: #### Electrical Characteristics * **Current Rating:** Typically 1A to 3A per pin. * **Voltage Rating:** 250V AC/DC. * **Contact Resistance:** $\le$ 15m$\Omega$ - 30m$\Omega$ max. * **Insulation Resistance:** $\ge$ 1000M$\Omega$ at 500V DC. #### Physical Material * **Insulator:** PBT (Polybutylene Terephthalate) or similar thermoplastic (UL94V-0 rated). * **Contacts:** Phosphor Bronze or Copper Alloy. * **Plating:** Gold plating on the contact area for superior conductivity; Tin plating on the solder tails. * **Shell:** Steel or Brass with Nickel or Tin plating for EMI/RFI shielding. --- ### 4. Application Areas Because of the **Right Angle (R)** design, this part is ideal for: 1. **Peripheral Ports:** Standard I/O interfaces on the back of industrial computers. 2. **Networking:** Telecommunication switches and routers. 3. **Medical Equipment:** High-reliability signal transmission in diagnostic tools. 4. **Embedded Systems:** Connecting daughtercards to a main motherboard where vertical space is limited. --- ### 5. Design Considerations ```markdown * Footprint: Ensure the PCB drill pattern matches the 16-pin pitch (usually 2.77mm or high-density 2.29mm). * Mechanical Stress: The "BD" board-lock helps absorb the force of plugging/unplugging to prevent solder joint cracking. * Shielding: Ensure the metal shell is grounded to the PCB plane to reduce electronic noise. ```
