The **MPIA2510V2-R68-R** is a high-performance, miniature power inductor designed for surface-mount applications. It is part of the MPIA series by **Eaton (formerly Bussmann)**, specifically engineered for automotive and industrial electronics where high power density and reliability are required. --- ### 1. Part Number Breakdown The nomenclature describes the specific physical and electrical characteristics of the component: | Code Segment | Description | Value | | :--- | :--- | :--- | | **MPIA** | Series Name | Miniature Power Inductor (Automotive Grade) | | **2510** | Dimensions (LxW) | 2.5 mm x 2.0 mm | | **V2** | Version | Version 2 (Typically improved efficiency/materials) | | **R68** | Inductance | 0.68 µH | | **R** | Tolerance/Packaging | Standard RoHS compliant / Tape & Reel | --- ### 2. Electrical Characteristics These parameters define how the inductor performs under load: * **Inductance:** 0.68 µH (measured at 100 kHz). * **Isat (Saturation Current):** The current level where inductance drops by a specific percentage (usually 30%). For this part, it is typically around **4.8A to 5.2A**. * **Irms (Heating Current):** The DC current that causes a temperature rise (usually 40°C). This is typically around **3.5A to 4.0A**. * **DCR (DC Resistance):** Usually measured in mΩ. This part features very low resistance (approx. **34-40 mΩ**) to minimize power loss. * **Operating Temperature:** -40°C to +125°C (standard for automotive grade). --- ### 3. Key Physical Features * **Construction:** Metal composite core. This provides "soft saturation" characteristics, meaning the inductance doesn't drop off abruptly when current increases. * **Shielding:** It is magnetically shielded, which reduces Electromagnetic Interference (EMI) with surrounding components. * **Footprint:** 2.5mm x 2.0mm with a low profile (1.0mm height), making it ideal for thin devices like smartphones or automotive sensors. --- ### 4. Typical Applications This inductor is commonly used in DC-DC converters and Point-of-Load (POL) modules for: 1. **Automotive Infotainment:** Powering screens and processors. 2. **ADAS (Advanced Driver Assistance Systems):** Powering cameras and radar modules. 3. **Industrial IoT:** Compact sensor nodes requiring efficient power management. 4. **Mobile Devices:** High-frequency switching regulators. --- ### 5.
