Based on the technical nomenclature commonly used in the electronics industry, **A-USBPA-R** typically refers to a **USB 2.0 Type A Plug (Male)** connector designed for PCB (Printed Circuit Board) mounting, often manufactured by companies like Adam Tech. Below is a detailed breakdown of the electronic parts, specifications, and physical characteristics of this component. --- ### 1. General Specifications The A-USBPA-R is a standard interface component used to provide a physical connection point for USB cables or to allow a device to be plugged directly into a USB port. | Feature | Specification | | :--- | :--- | | **Connector Type** | USB Type A | | **Gender** | Plug (Male) | | **USB Version** | 2.0 (High Speed) | | **Mounting Type** | Through-Hole (Right Angle or Straight) | | **Orientation** | Horizontal (Right Angle) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Material Composition To ensure conductivity and durability, the component is constructed from several specific materials: * **Insulator:** High-temperature thermoplastic (usually PBT or LCP), typically UL94V-0 rated for fire safety. * **Contacts:** Copper alloy (Phosphor Bronze or Brass). * **Contact Plating:** * **Gold** on the mating area (to prevent oxidation and ensure low resistance). * **Tin** on the solder tails (for easy soldering to the PCB). * **Shell:** Steel or Copper alloy with Nickel plating for EMI/RFI shielding. --- ### 3. Electrical Characteristics These parameters define the safe operating limits for the connector. | Parameter | Value | | :--- | :--- | | **Voltage Rating** | 30V AC/DC | | **Current Rating** | 1.0A to 1.5A per contact | | **Contact Resistance** | < 30 mΩ | | **Insulation Resistance** | > 1000 MΩ | | **Dielectric Strength** | 500V AC for 1 minute | --- ### 4. Pinout Configuration Standard USB 2.0 Type A connectors consist of 4 primary pins: 1. **VCC (+5V):** Power supply. 2. **D-:** Data Negative. 3. **D+:** Data Positive. 4. **GND:** Ground. 5. **Shield:** Connected to the outer metal casing for noise reduction. --- ### 5. Common Applications * **USB Flash Drives:** The primary connector for thumb drives. * **Peripheral Dongles:** Wireless mouse/keyboard receivers. * **Embedded Systems:** Providing a plug-in interface for microcontrollers. * **Charging Devices:** Integrated into compact wall chargers or power banks. ---
