Based on the technical nomenclature for electronic components, the **M2PHSH-153-R2** is a specialized high-density connector, typically part of a pin header or board-to-board interconnect system. These parts are fundamental in routing signals between PCBs (Printed Circuit Boards). --- ### 1. General Specifications While specific manufacturers (like Adam Tech or Samtec) may use variations of this part number, the code generally breaks down into the following physical attributes: | Feature | Specification Details | | :--- | :--- | | **Component Type** | Male Pin Header (PH) | | **Pitch** | Typically 2.00mm (M2) | | **Mounting Style** | Surface Mount (SMT) or Through-Hole (SH/H) | | **Pin Count** | 153 Pins (High Density) | | **RoHS Status** | Compliant (Indicated by R2 suffix) | --- ### 2. Key Electronic Properties High-density connectors like the M2PHSH-153-R2 are designed with specific electrical constraints to ensure signal integrity: 1. **Contact Resistance:** Usually rated at **20mΩ max**, ensuring minimal voltage drop across the connection. 2. **Current Rating:** Typically **1A to 2A per pin**. Due to the high pin count, the total current capacity is high, but thermal dissipation must be managed. 3. **Dielectric Withstanding Voltage:** Often rated for **500V AC/DC**, preventing arcing between the closely spaced pins. 4. **Insulation Resistance:** Usually **1000MΩ min**, ensuring no leakage current between adjacent signals. --- ### 3. Physical Construction The materials used are chosen for durability and conductivity: * **Insulator:** High-temperature thermoplastic (e.g., LCP or Nylon 6T) to withstand reflow soldering temperatures (up to 260°C). * **Contact Material:** Phosphor Bronze or Brass for a balance of flexibility and conductivity. * **Plating:** Usually Gold (Au) flash on the contact area to prevent oxidation and Tin (Sn) on the solder tails for better solderability. --- ### 4. Common Applications Due to the **153-pin** configuration, this part is rarely used for simple power delivery. It is found in: * **FPGA Mezzanine Cards:** High-speed data transfer between a daughterboard and a carrier. * **Industrial Automation:** Connecting PLC modules. * **Telecommunications:** High-density backplane signal routing. ---
