The **MLC05-R068M-RC** is a high-performance power inductor, typically used in surface-mount technology (SMT) applications. It is designed for power management circuits where high current handling and low core losses are required. --- ### 1. Technical Specifications The following table outlines the key electrical characteristics of this specific component: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Inductance** | 0.068 µH (68nH) | Measured at 100 kHz, 0.1V | | **Tolerance** | ±20% | Indicated by the "M" in the part number | | **Current Rating (Irms)** | ~25A - 30A | Varies slightly by manufacturer thermal limits | | **Saturation Current (Isat)** | ~45A - 55A | The point where inductance drops by 20-30% | | **DC Resistance (DCR)** | ~0.80 mΩ (Typical) | Extremely low resistance to minimize heat | | **Operating Temperature** | -40°C to +125°C | Includes self-heating effects | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying the physical and electrical properties: 1. **MLC**: Series code (usually signifying a Molded Low Profile Inductor). 2. **05**: Refers to the physical size (typically approx. 5.5mm x 5.2mm). 3. **R068**: The inductance value (R acts as a decimal point, 0.068µH). 4. **M**: Tolerance code (M = ±20%). 5. **RC**: RoHS Compliant. --- ### 3. Key Features & Construction * **Molded Construction:** The coil is embedded in a magnetic metal powder iron core. This "shielded" design results in very low acoustic noise and low magnetic leakage (EMI). * **High Saturation:** Unlike ferrite inductors, these molded types have a "soft" saturation characteristic, meaning they can handle high current spikes without a sudden loss of inductance. * **Low Profile:** The "05" series is designed to be very thin, making it ideal for compact consumer electronics like laptops and tablets. --- ### 4. Typical Applications This inductor is commonly found in the following circuits: * **DC-DC Converters:** Used in VRM (Voltage Regulator Modules) for CPUs and GPUs. * **Pol (Point of Load) Converters:** High-frequency power supplies. * **Battery Powered Devices:** Due to low DCR, it maximizes battery life by reducing power dissipation. * **Smartphones/Tablets:** Where space is limited but current demands are high. ---
