Based on the part number **M2CEC-275F-R2/Q**, this component belongs to a specialized category of **Rectangular Connectors** or **M-Series Micro-Connectors**, typically used in high-reliability industrial or aerospace applications. Below is a breakdown of the electronic and structural characteristics of this part. --- ## 1. Component Specification Overview | Feature | Description | | :--- | :--- | | **Component Type** | Rectangular Micro-Connector / PCB Header | | **Series** | M2CEC (Micro-Electronic Connector Series) | | **Contact Density** | High-density pitch (typically 1.27mm or 2.0mm) | | **Mounting Type** | Through-hole or Right-Angle PCB Mount | | **Reliability Rating** | Industrial/Military Grade (Q-Suffix) | --- ## 2. Technical Breakdown of the Part Number The alphanumeric code provides specific details regarding the geometry and material properties: ### **M2CEC** (Series Prefix) * Indicates the family of connectors. These are usually **Micro-Pitch** connectors designed for compact electronic assemblies where space is limited but signal integrity is crucial. ### **275** (Contact/Size Code) * Refers to either the specific shell size or the number of contacts. In this series, "275" often designates a specific arrangement or a high-pin count configuration. ### **F** (Gender/Type) * **F** stands for **Female** (Socket contacts). This indicates the part is designed to receive pins from a mating "M" (Male) connector. ### **R2** (Revision or Mounting Style) * **R** usually denotes **Right-Angle** orientation. * **2** indicates the revision level or a specific tail length for PCB soldering. ### **Q** (Quality Grade) * The **/Q** suffix is a critical electronic indicator. It signifies **Qualification** or **Quality Assurance** testing. This usually means the part has undergone extra screening for thermal cycling, vibration resistance, and outgassing. --- ## 3. Key Electronic Properties 1. **Contact Resistance:** Typically very low (under 10-20 mΩ) to ensure minimal voltage drop across the connection. 2. **Insulation Resistance:** Usually rated at 5000 MΩ or higher to prevent leakage between adjacent high-density pins. 3. **Dielectric Withstanding Voltage:** Designed to handle spikes (often up to 600V AC at sea level) without arcing. 4. **Current Rating:** Despite the small size, these contacts are usually rated for **1A to 3A** per pin, depending on the wire gauge or PCB trace width. --- ## 4. Common Applications * **Avionics:** Control systems where vibration resistance is mandatory. * **Medical Imaging:** High-density signal routing in ultrasound or MRI sensors. * **Defense Systems:** Ruggedized handheld communications or telemetry units. ---
