The **MLZ2012M100HT000** is a multilayer inductor specifically designed for decoupling circuits in power lines. It is manufactured by **TDK Corporation** and belongs to the MLZ series (Multilayer Inductors for Power Lines). --- ### 1. Technical Specifications The table below highlights the core electrical and physical characteristics of the component: | Parameter | Value / Specification | |:---|:---| | **Inductance** | 10 $\mu$H | | **Tolerance** | ±20% | | **Rated Current (Max)** | 150 mA | | **DC Resistance (Max)** | 0.45 $\Omega$ | | **Self-Resonant Frequency** | 40 MHz (Typical) | | **Operating Temperature** | -55°C to +125°C | | **Package Size (EIA)** | 0805 | | **Package Size (Metric)** | 2012 (2.0 x 1.25 x 1.25 mm) | --- ### 2. Key Features and Construction The "MLZ" series is engineered to bridge the gap between standard signal inductors and power inductors. * **Multilayer Technology:** Unlike wire-wound inductors, this part is created by layering ceramic and conductive materials, resulting in a compact, monolithic structure with high reliability. * **DC Superposition Characteristics:** This part is optimized to maintain its inductance even when a DC current is applied, which is critical for power line filtering. * **Magnetic Shielding:** The closed magnetic circuit design minimizes EMI (Electromagnetic Interference) and prevents crosstalk with neighboring components. * **Automotive Grade:** The "H" in the part number often signifies high-reliability testing, making it suitable for automotive applications (AEC-Q200 compliant). --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying variants: | Code | Meaning | |:---|:---| | **MLZ** | Series Name (Multilayer Inductor for Power Lines) | | **2012** | Dimensions (2.0mm x 1.25mm) | | **M** | Characteristic Type (Standard) | | **100** | Inductance Value (100 = $10 \times 10^0 = 10 \mu$H) | | **H** | High reliability / Automotive Grade | | **T000** | Packaging Style (Taping/Reel) | --- ### 4. Common Applications Due to its low resistance and high-frequency noise suppression, it is commonly used in: * **Smartphones and Tablets:** Decoupling power supply lines to the CPU or GPU. * **Automotive Electronics:** Infotainment systems and ADAS sensors. * **Industrial Modules:** DC-DC converter output filtering where space is limited.
