The **MPIA4015V2-1R0-R** is a high-performance, automotive-grade power inductor manufactured by **Eaton (formerly Bussmann)**. It belongs to the MPIA4015V2 series, which is characterized by its miniature footprint and high current handling capabilities. --- ### 1. Technical Specifications The following table summarizes the core electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Inductance** | 1.0 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | 18.0 mΩ (Typical) / 22.0 mΩ (Max) | | **Rated Current (Irms)** | 6.2 Amps | | **Saturation Current (Isat)** | 8.2 Amps | | **Operating Temperature** | -40°C to +125°C | | **Dimensions (L x W x H)** | 4.75mm x 4.06mm x 1.55mm | | **AEC-Q200 Qualified** | Yes (Grade 3) | --- ### 2. Key Features * **Metal Composite Construction:** The core is made of a metal powder composite. This provides a "soft" saturation characteristic (it doesn't lose inductance abruptly) and helps minimize acoustic noise. * **Low Profile:** At only 1.55mm high, it is ideal for thin electronic assemblies where vertical space is limited. * **High Efficiency:** Low DCR helps reduce power loss and heat generation, which is critical for battery-powered or high-efficiency DC-DC converters. * **Shielded Design:** The molded construction provides magnetic shielding, reducing Electromagnetic Interference (EMI) to surrounding components. --- ### 3. Part Number Breakdown The nomenclature reveals specific details about the component: * **MPIA**: Metal Power Inductor, Automotive Grade. * **4015**: Physical size (approx. 4.0mm x 1.5mm height). * **V2**: Version/Series 2 (improved materials/design). * **1R0**: Inductance value (1.0 microhenries). * **R**: RoHS compliant. --- ### 4. Common Applications Due to its AEC-Q200 certification and robust design, this part is frequently used in: * **Automotive Electronics:** Infotainment systems, ADAS modules, and LED lighting drivers. * **Computing:** Power supplies for CPUs and GPUs in industrial PCs. * **Mobile Devices:** Handheld terminals and high-density DC-DC converters.
