The **MLC10-R68M-RC** is a high-current, shielded power inductor typically used in DC-DC converter applications. It is designed for high-frequency power supplies where low core loss and high saturation currents are required. ### 1. Part Number Breakdown Understanding the alphanumeric code helps identify the component's specifications: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **MLC10** | Series/Size | Molded Inductor, Size 10 (approx. 10mm x 11mm) | | **R68** | Inductance Value | 0.68 µH (Microhenries) | | **M** | Tolerance | ±20% | | **RC** | Compliance | RoHS Compliant | --- ### 2. Technical Specifications The following table outlines the typical electrical characteristics for this class of molded inductor: | Parameter | Value (Typical) | | :--- | :--- | | **Inductance** | 0.68 µH | | **DC Resistance (DCR)** | ~2.5 mΩ (Max) | | **Rated Current (Irms)** | ~25A - 30A (Temperature rise based) | | **Saturation Current (Isat)** | ~40A - 50A (L drops by 20-30%) | | **Operating Temperature** | -40°C to +125°C | | **Construction** | Metal Alloy Powder (Molded) | --- ### 3. Key Electronic Features * **Shielded Construction:** The magnetic metal powder core provides self-shielding, which significantly reduces EMI (Electromagnetic Interference) compared to unshielded inductors. * **Soft Saturation:** Unlike ferrite cores that lose inductance abruptly when current limits are exceeded, this metal alloy core exhibits "soft saturation," meaning the inductance drops gradually. * **Low DCR:** The use of thick copper wire ensures low Direct Current Resistance, which minimizes power loss and heat generation. * **High Frequency Performance:** Optimized for switching frequencies ranging from 100 kHz up to 5 MHz. --- ### 4. Typical Applications This component is found in circuits requiring high efficiency and compact footprints: 1. **Voltage Regulator Modules (VRM):** Used in CPU and GPU power delivery on motherboards. 2. **Point of Load (POL) Converters:** Distributed power systems in telecommunications. 3. **Battery Powered Devices:** High-efficiency buck/boost converters for portable electronics. 4. **Automotive Electronics:** Infotainment and ADAS power rails (if AEC-Q200 qualified). ---
