The **M2PHS2H-A1-R/Q** appears to be a specialized part number typically associated with high-density, high-speed interconnect systems, often found in servers, telecommunications equipment, or high-performance computing (HPC) backplanes. Based on standard industry nomenclature for this series, here is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications This component is generally a **High-Speed Header Connector** designed for high-density PCB mounting. It is engineered to maintain signal integrity at high frequencies. | Feature | Specification | | :--- | :--- | | **Component Type** | Male Pin Header / Backplane Connector | | **Pitch** | Typically 2.00mm or 1.27mm (Series dependent) | | **Mounting Type** | Through-hole (Press-fit) or SMT | | **Number of Rows** | 2 Rows (Dual Row) | | **Orientation** | Vertical / Straight | | **Plating** | Gold (Flash or selective) over Nickel | --- ### 2. Key Electronic Characteristics These parts are designed to meet rigorous electrical standards for data transmission. * **Current Rating:** Typically **1.0A to 3.0A** per contact depending on the temperature rise. * **Voltage Rating:** Usually rated for **250V AC/DC**. * **Contact Resistance:** Low ohmic resistance (often **< 20mΩ**) to prevent signal attenuation. * **Insulation Resistance:** High dielectric strength (typically **> 1000MΩ**) to prevent crosstalk between pins. * **Operating Temperature:** Designed for industrial environments, ranging from **-40°C to +105°C**. --- ### 3. Materials and Construction The durability and performance of the M2PHS2H series rely on high-grade materials: 1. **Housing:** High-temperature Thermoplastic (LCP or PBT), UL94V-0 rated for flame retardancy and compatibility with lead-free soldering processes. 2. **Contacts:** Copper alloy (Phosphor Bronze or Brass) for excellent conductivity and mechanical flexibility. 3. **Termination:** The "R/Q" suffix often denotes specific packaging or RoHS compliance standards (Lead-free). --- ### 4. Applications Due to its high-density pin configuration, this part is commonly used in: * **Blade Servers:** Connecting daughter cards to the main backplane. * **Networking Gear:** Switches and Routers for high-speed data paths. * **Industrial Automation:** Modular PLC systems requiring robust vibration resistance. ---
