The **M2CEC-1350D-R** is a specialized electronic component, typically categorized as a **Chip Inductor** (specifically a Metal Composite Type). These parts are critical for power management circuits in high-density electronic devices. --- ### 1. Key Technical Specifications Below are the primary electrical and physical characteristics of this component: | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Metal Composite Power Inductor | | **Inductance** | 1.35 µH (Microhenries) | | **Mounting Type** | Surface Mount (SMD) | | **Core Material** | Metal Alloy (Iron-based powder) | | **Tolerance** | ±20% | | **Shielding** | Magnetically Shielded | --- ### 2. Physical Design & Composition The "M2CEC" series is designed to handle high current in a compact footprint. * **Metal Composite Core:** Unlike traditional ferrite inductors, these use a metal alloy powder. This allows for **soft saturation** characteristics, meaning the inductance drops gradually rather than abruptly as current increases. * **Molded Construction:** The wire coil is embedded directly into the metal powder body and pressed. This results in a rugged, shielded structure that minimizes acoustic noise (buzzing) and electromagnetic interference (EMI). --- ### 3. Application Areas These parts are generally found in DC-DC converters and Power Management Integrated Circuits (PMICs). * **Computing:** CPU and GPU voltage regulator modules (VRMs). * **Mobile Devices:** High-efficiency power stages in smartphones and tablets. * **Industrial:** Compact power supplies requiring high thermal stability. --- ### 4. Comparison: Metal Composite vs. Ferrite | Attribute | Metal Composite (M2CEC) | Standard Ferrite | | :--- | :--- | :--- | | **Saturation** | Soft (Gradual) | Hard (Sudden) | | **EMI Shielding** | Excellent | Moderate | | **DC Resistance** | Very Low | Low | | **Current Handling** | High for size | Moderate | --- ### 5. Part Number Breakdown (Generalized) While manufacturers have unique codes, the suffixing usually denotes: * **1350:** Represents the Inductance value (1.35 µH). * **D:** Often refers to the size/height profile or tolerance class. * **R:** Usually indicates **Tape and Reel** packaging for automated pick-and-place assembly.
