### MPIA4015V2-100-R: Electronic Specifications and Overview The **MPIA4015V2-100-R** is a high-performance, automotive-grade power inductor manufactured by Eaton (formerly Cooper Bussmann). It belongs to the MPIA4015V2 series, which is characterized by its miniature footprint and high current-handling capabilities. --- ### 1. Key Technical Specifications The following table outlines the primary electrical and physical characteristics of this specific component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 10.0 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | 2.1 A (Typical) | | **Saturation Current (Isat)** | 2.7 A (Typical) | | **DC Resistance (DCR)** | 134 mΩ (Max) | | **Self-Resonant Frequency** | 21 MHz | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | 4.0mm x 4.0mm x 1.5mm | --- ### 2. Core Features and Technology * **Automotive Grade:** It is **AEC-Q200 Grade 1** qualified, meaning it is tested for high reliability in harsh environments, including extreme temperature fluctuations and mechanical vibrations. * **Metal Composite Construction:** The inductor uses a metal powder core technology. This provides a "soft saturation" characteristic, where inductance drops gradually rather than abruptly as current increases. * **Magnetic Shielding:** The design is naturally shielded, which minimizes Electromagnetic Interference (EMI) with surrounding components on the PCB. * **Low Profile:** With a height of only 1.5mm, it is ideal for thin electronic assemblies. --- ### 3. Application Use Cases The MPIA4015V2-100-R is primarily used in DC-DC converters and power management modules. Common applications include: 1. **Automotive Electronics:** Infotainment systems, Advanced Driver Assistance Systems (ADAS), and instrument clusters. 2. **Industrial IoT:** Compact sensors and handheld devices requiring ruggedized power components. 3. **Computing:** Point-of-load (POL) converters for distributed power architectures. --- ### 4.
