The **MHR68FAJ-R** is a specific electronic component, typically categorized as a **High-Density Rectangular Connector** or a specialized **PCB Mount Header**, often used in industrial or automotive electronics. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This part belongs to the category of board-to-wire or board-to-board interconnects designed for space-constrained environments. | Feature | Description | | :--- | :--- | | **Component Type** | Male Header / Pin Connector | | **Pitch (Spacing)** | Typically 1.27mm or 2.00mm (depends on specific series variant) | | **Number of Pins** | 68 Pins | | **Orientation** | Right-Angle (R) / Horizontal Mount | | **Termination Style** | Through-hole or SMT (Surface Mount Technology) | ### 2. Key Electronic Properties The functionality of the MHR68FAJ-R is defined by its electrical limits and materials: * **Current Rating:** Usually rated for **0.5A to 1.0A per contact**, making it suitable for signal transmission rather than power delivery. * **Voltage Rating:** Generally around **125V AC/DC**. * **Contact Resistance:** Typically low (under **30mΩ**) to ensure signal integrity. * **Insulation Resistance:** High threshold (usually **>500MΩ**) to prevent leakage between adjacent pins. ### 3. Physical & Material Composition The "FAJ-R" suffix often provides clues regarding the mounting and material specifications: 1. **Housing:** Made of high-temperature thermoplastic (e.g., LCP or Nylon 6T) to withstand reflow soldering temperatures. 2. **Contacts:** Copper alloy base plated with **Gold (Au)** over Nickel, providing superior corrosion resistance and conductivity. 3. **Right-Angle Design (-R):** The pins are bent at a 90-degree angle, allowing the connector to sit flush against the edge of a PCB, which is ideal for side-entry cables or daughter-card mating. ### 4. Typical Applications Due to the high pin count (68 pins), this part is commonly found in: * **PCMCIA Interfaces:** Older laptop expansion slots. * **SCSI Connections:** High-speed data transfer interfaces for drives. * **Industrial PLC Modules:** Connecting logic boards to I/O panels. * **Embedded Systems:** High-density signal routing between stacked PCBs. ---
