Technical Specifications The following table outlines the core electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.47 µH | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~11 - 13 mΩ (Typical) | | **Saturation Current (Isat)** | ~8.0 - 9.5 A (Typical) | | **Temperature Rise Current (Irms)** | ~7.0 - 8.5 A (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | 1210 / 1212 (Approx. 3.0 x 3.0 x 1.2 mm) | --- ### 2. Component Breakdown (Naming Convention) The part number can be decoded to understand its construction: * **MLPC**: Series designation (Molded Low Profile Power Choke). * **12**: Physical size code (often referring to height or footprint dimensions). * **R47**: Inductance value (R serves as a decimal point; 0.47 microhenries). * **M**: Tolerance (Standard ±20%). * **RC**: RoHS Compliant. --- ### 3. Key Features & Construction * **Molded Structure:** Unlike traditional wire-wound inductors, this part uses a metal powder molding technology. This provides excellent magnetic shielding and reduces acoustic noise (buzzing). * **High Saturation:** The metal powder core allows the inductor to handle high peak currents without the inductance dropping off sharply. * **Low Profile:** The "LP" in the name stands for Low Profile, making it ideal for thin electronic devices like smartphones, tablets, and SSDs. * **Low DCR:** Designed to minimize power loss as heat, increasing the overall efficiency of the power circuit. --- ### 4. Typical Applications This inductor is primarily used in **Switching Mode Power Supplies (SMPS)** for: 1. **CPU/GPU Power Rails:** Providing stable current to high-speed processors. 2. **DC-DC Buck Converters:** Stepping down voltage in battery-operated devices. 3. **Communication Equipment:** Filtering noise in RF and data transmission modules.
