Technical Specifications The following table summarizes the key electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 6.8 µH | | **Tolerance** | ±15% | | **DC Resistance (DCR)** | 0.45 Ω (±30%) | | **Rated Current (Isat/Itemp)** | 150 mA | | **Self-Resonant Frequency** | 40 MHz | | **Case Size (EIA/Metric)** | 0805 / 2012 | | **Dimensions (L x W x T)** | 2.00mm x 1.25mm x 1.25mm | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Key Features and Construction * **Multilayer Ferrite Technology:** Unlike wire-wound inductors, this part is constructed by layering ferrite paste and conductive internal electrodes. This results in a monolithic structure that is highly reliable and physically robust. * **Magnetic Shielding:** The multilayer structure inherently provides magnetic shielding, which prevents electromagnetic interference (EMI) from affecting surrounding components on a dense PCB. * **Low DC Resistance:** Despite its small 0805 footprint, it maintains a low DCR to minimize power loss and heat generation. * **"W" Series Characteristics:** The MLZ series is optimized for power lines, offering higher current handling capabilities compared to standard signal-line multilayer inductors. --- ### 3. Application Use Cases The MLZ2012N6R8LT is typically used in the following scenarios: 1. **Decoupling:** Filtering high-frequency noise in the power supply lines of ICs (Application Processors, Baseband chips). 2. **Smartphones & Tablets:** Used in PMICs (Power Management Integrated Circuits) where height and board space are restricted. 3. **Battery Powered Devices:** Ideal for IoT modules and wearables due to its balance of inductance and small form factor. --- ### 4. Circuit Symbol Representation In a schematic, this part is represented as a standard inductor, often with a parallel line to indicate its ferrite core. ```markdown L1 (6.8uH) ----(UUUUU)---- MLZ2012 ``` ---
