The **M2CEC-2225F-R2/Q** is a specialized electronic component, typically categorized as a high-density, high-performance interconnect solution (connector). While part numbering can vary by manufacturer (such as Mill-Max or Hirose), this specific series generally refers to an **M.2 Card Edge Connector**. Below is a breakdown of the electronic and mechanical characteristics of this component. --- ### 1. General Specifications The "M2CEC" series is designed to interface with M.2 (formerly NGFF) modules used in modern computing. | Feature | Description | | :--- | :--- | | **Component Type** | M.2 (NGFF) Card Edge Connector | | **Pitch** | 0.50 mm (standard for M.2) | | **Mounting Type** | Surface Mount (SMT) | | **Number of Pins** | Varies (Typically 67 or 75 positions) | | **Termination** | Right Angle / Horizontal | --- ### 2. Key Part Number Breakdown * **M2CEC**: Series identifier (M.2 Card Edge Connector). * **22**: Often refers to the width of the card (22mm). * **25**: Can indicate the height of the connector (e.g., 2.25mm or 2.5mm profile). * **F**: Likely indicates "Female" (Socket) or "Flash" (Gold plating type). * **R2**: Revision 2 or Reel packaging specifications. * **Q**: Often a qualification code or specific keying (e.g., Key M, Key B, or Key E). --- ### 3. Electrical Characteristics These connectors are engineered to handle high-speed data signals with minimal interference. * **Current Rating:** Typically 0.5A per pin. * **Voltage Rating:** 50V AC/DC. * **Contact Resistance:** Max 50mΩ (standard). * **Insulation Resistance:** Min 500MΩ. * **Dielectric Withstanding Voltage:** 300V AC for 1 minute. --- ### 4. Physical & Material Properties To ensure durability and signal integrity, the materials used are high-grade: * **Housing:** High-temperature thermoplastic (LCP - Liquid Crystal Polymer), UL94V-0 rated (flame retardant). * **Contacts:** Copper Alloy. * **Plating:** Gold plating on the contact area to prevent oxidation; Tin plating on the solder tails. * **Keying:** The physical notch in the connector prevents the wrong type of M.2 card (SATA vs. NVMe) from being inserted. --- ### 5. Common Applications This part is found in devices requiring compact, high-speed storage or wireless communication modules: * **Solid State Drives (SSD):** NVMe and SATA M.2 drives. * **Wireless Modules:** Wi-Fi 6/7 and Bluetooth cards. * **Industrial Computing:** Embedded motherboards and IoT gateways. ---
