The **ML2010EL-R20-JT** is a high-precision, surface-mount (SMD) **Power Inductor**, commonly used in power management circuits. It is part of the ML family of metal alloy inductors designed for high-current efficiency and low electromagnetic interference (EMI). --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of the component: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Inductance** | 0.20 µH | Nominal value at 1MHz | | **Tolerance** | ±20% | Standard "M" or "J" class tolerance | | **Case Size** | 2010 (Metric) | 2.0mm x 1.0mm | | **Height** | 1.0mm (Max) | Low profile design | | **DC Resistance (DCR)** | ~10-15 mΩ | Typical low resistance for efficiency | | **Saturation Current ($I_{sat}$)** | ~5.0 - 7.0 A | Current where inductance drops 30% | | **Rated Current ($I_{rms}$)** | ~3.5 - 4.5 A | Based on temperature rise (40°C) | | **Material** | Metal Alloy | Molded construction for magnetic shielding | --- ### ### Key Features 1. **Metal Alloy Construction:** Unlike traditional ferrite inductors, these use a metal composite powder. This allows for **soft saturation** (the inductance drops gradually rather than abruptly when current increases), preventing sudden circuit failure. 2. **Magnetic Shielding:** The molded body acts as a natural shield, significantly reducing leaked magnetic flux and minimizing EMI in compact PCB layouts. 3. **Low DCR:** The internal flat-wire or thick-film technology ensures very low resistance, which minimizes heat dissipation and maximizes battery life in portable devices. 4. **High Frequency Stability:** Optimized for high-frequency DC-DC converters (switching frequencies above 1MHz). --- ### ### Typical Applications This part is primarily found in high-density power modules where space is limited but current demand is high. * **Smartphones & Tablets:** Point-of-Load (POL) converters for CPUs/GPUs. * **Wearables:** Compact power supplies for IoT sensors. * **SSD/Storage:** Power rails for high-speed flash controllers. * **DC-DC Converters:** Buck/Boost regulators in battery-powered equipment. --- ### ### Marking & Decoding the Part Number * **ML:** Series code (Metal Alloy/Multilayer type). * **2010:** Dimensions (2.0mm length x 1.0mm width). * **EL:** Product specific characteristic (e.g., height or material type). * **R20:** Inductance value ($R$ = Decimal). $0.20$ µH. * **J/T:** Tolerance and Packaging (T usually denotes Tape and Reel).
