Key Technical Specifications | Parameter | Value | Notes | | :--- | :--- | :--- | | **Inductance** | 6.8 µH | Rated at 2MHz | | **Tolerance** | ±20% | Standard for power inductors | | **Rated Current** | 250 mA | Maximum continuous current | | **DC Resistance (DCR)** | 0.45 Ω (±30%) | Low resistance to minimize power loss | | **Case Size (EIA/Metric)** | 0805 / 2012 | 2.0mm x 1.25mm x 1.25mm | | **Operating Temp** | -55°C to +125°C | Suitable for industrial applications | | **Type** | Ferrite Core | Multilayer construction | --- ### 2. Physical Construction and Series Characteristics The MLZ series utilizes a **multilayer structure**, which means the coil is printed on ferrite sheets and stacked. This offers several advantages over traditional wire-wound inductors: * **Shielded Design:** The magnetic flux is contained within the ferrite body, reducing electromagnetic interference (EMI) with neighboring components. * **High Reliability:** No external wires that can break under vibration or thermal stress. * **"H" Characteristic:** The "H" in the part number indicates a **High-Current** type within the series, providing better DC superimposition characteristics (meaning the inductance stays more stable as current increases). --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying variants: | Code | Meaning | | :--- | :--- | | **MLZ** | Multilayer Inductor for Power Lines (Z-series) | | **2012** | Dimensions (2.0mm length x 1.25mm width) | | **M** | Product Material (Internal ferrite blend) | | **6R8** | Inductance Value (6.8 microhenries) | | **H** | Characteristic Type (High Current) | | **T000** | Packaging (T = Taping / 000 = Standard) | --- ### 4. Typical Applications This specific component is usually found in mobile devices, communication equipment, and consumer electronics for: * **Power Supply Decoupling:** Preventing noise from a high-speed IC from entering the power rail. * **DC-DC Converters:** Used in low-power voltage regulation stages. * **Signal Conditioning:** Filtering ripple and high-frequency noise in sensitive analog or digital circuits.
