The **MLPCH12-R24M-RC** is a high-performance, surface-mount (SMD) power inductor commonly used in compact electronic power management circuits. It is part of the MLPCH series, which typically features a metal composite core for high current handling and low core losses. --- ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.24 µH | | **Tolerance** | ±20% | | **Inductance Code** | R24 | | **Case Size** | 12 (Typically 2.5mm x 2.0mm) | | **Core Material** | Metal Composite (Iron Powder) | | **RoHS Compliant** | Yes (-RC suffix) | --- ## Key Features ### 1. Metal Composite Construction Unlike traditional ferrite inductors, this part uses a metal composite core. This allows for: * **Soft Saturation:** The inductance decreases gradually as current increases, rather than dropping sharply. * **High Current Density:** Higher current handling capability in a smaller footprint. ### 2. Shielded Design The part is magnetically shielded. This minimizes **Electromagnetic Interference (EMI)**, making it ideal for high-density PCB layouts where components are placed close together. ### 3. Low DCR (DC Resistance) The internal copper winding is designed to have very low resistance, which minimizes power loss (heat) and improves the overall efficiency of the power converter. --- ## Circuit Applications This inductor is primarily designed for **DC-DC Converters** and voltage regulation modules. * **Buck Converters:** Used as the energy storage element in step-down regulators. * **Smartphone/Wearables:** Due to its small form factor and high efficiency, it is frequently used in mobile battery-powered devices. * **Computing:** Used in point-of-load (POL) power supplies for CPUs and GPUs. --- ## Typical Part Number Breakdown | Part Segment | Meaning | | :--- | :--- | | **MLPCH** | Series Series (Metal Low Profile High Current) | | **12** | Size Code (Physical dimensions) | | **R24** | Inductance Value (0.24 µH) | | **M** | Tolerance (M = ±20%) | | **RC** | RoHS Compliant / Lead-Free |
