The **MIPSZ2012D2R2** is a specific electronic component belonging to the category of **Multilayer Chip Power Inductors** (specifically the MIPSZ series). These are designed primarily for power supply circuits in mobile devices, such as smartphones, tablets, and DC-DC converters. --- ## 1. Technical Specifications The part number follows a standard nomenclature used by manufacturers like **FDK** or **TDK**. Below are the core parameters: | Parameter | Specification | | :--- | :--- | | **Inductance** | 2.2 μH | | **Tolerance** | ±20% (M) | | **Case Size** | 2012 (Metric) / 0805 (Inch) | | **Dimensions** | 2.0 x 1.25 x 1.0 mm | | **Rated Current** | Approx. 800mA - 1200mA (varies by load) | | **DC Resistance (DCR)** | Typ. 0.11 Ω - 0.15 Ω | | **Material** | Ferrite core, Multilayer | --- ## 2. Key Features ### A. Multilayer Technology Unlike wire-wound inductors, this part is created by layering ceramic sheets and internal electrode patterns. * **Benefit:** High reliability and compact size (0805 footprint). * **Shielding:** The closed magnetic circuit structure reduces EMI (Electromagnetic Interference) leakage. ### B. DC Superposition Characteristics The "Power" designation means this inductor is optimized to maintain its inductance value even when high DC current flows through it. It has a "soft saturation" curve. ### C. Low Profile With a thickness of approximately 1.0mm, it is ideal for slim portable electronics where PCB height is restricted. --- ## 3. Pinout and Footprint As an 0805 surface-mount device (SMD), it features two termination pads. ```markdown [Pad 1] ----- [Ferrite Body] ----- [Pad 2] (Input) (2.2uH Coil) (Output) ``` --- ## 4. Typical Applications * **DC-DC Converters:** Used as the storage element in buck/boost converters. * **Power Management Units (PMIC):** Filtering high-frequency noise from power rails. * **Mobile Devices:** Power circuits for CPUs, LCD displays, and wireless modules. ---
