The **M2REB-S43-R** is a specific part number typically associated with high-performance **M.2 (NGFF) Connectors**, often manufactured by companies like **Yamaichi Electronics**. These components are critical in modern computing for interfacing SSDs, Wi-Fi cards, and cellular modules with motherboards. --- ### 1. Key Technical Specifications The part number defines the physical and electrical characteristics of the socket. Below is a breakdown of the typical specifications for this series: | Feature | Specification | |:---|:---| | **Connector Type** | M.2 (Next Generation Form Factor) | | **Interface Style** | Card Edge Connector (Right Angle) | | **Number of Positions** | 67-Pin or 75-Pin (depending on keying) | | **Pitch** | 0.50 mm | | **Mounting Type** | Surface Mount (SMT) | | **Keying** | Typically "B" Key or "M" Key (check datasheet for S43 suffix) | | **Height** | 4.3mm (Standard profile) | --- ### 2. Component Composition The electronic part consists of three primary material groups: 1. **Contacts:** Usually made of **Copper Alloy** with **Gold plating** over Nickel. Gold is used to ensure low contact resistance and prevent oxidation over high-speed data cycles. 2. **Insulator/Housing:** High-temperature thermoplastic (e.g., LCP - Liquid Crystal Polymer) designed to withstand **Reflow Soldering** temperatures (approx. 260°C). 3. **Solder Tabs/Pegs:** Metal tabs on the sides of the connector that provide mechanical stability to the PCB, ensuring the connector doesn't rip off when a module is inserted. --- ### 3. Application Use Cases This connector acts as the bridge for high-speed protocols. Its internal electronic design supports: * **PCIe (Peripheral Component Interconnect Express):** Up to Gen 3 or Gen 4 speeds. * **SATA 3.0:** For M.2 SATA SSDs. * **USB 3.0/HS:** Often used when the M.2 slot hosts a WWAN (4G/5G) module. --- ### 4. Part Number Breakdown (Typical) While naming conventions vary slightly by manufacturer, the code generally follows this logic: ```text M2 : Series (M.2 Type) REB: Connector Orientation/Style S43: Height (4.3mm Profile) R : Packaging (Tape & Reel for automated assembly) ```
