The **ASPI-2012-R68** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC conversion and power management circuits. It is manufactured by Abracon. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical properties: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.68 µH (Microhenries) | | **Tolerance** | ±30% (denoted by the "N" tolerance standard typically) | | **Case Size** | 2012 (2.0mm x 1.2mm) | | **Height** | 1.0 mm (Max) | | **DC Resistance (DCR)** | ~40 mΩ (Typical) | | **Saturation Current (Isat)** | ~2.5 A to 3.0 A | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Physical Construction The ASPI-2012 series is built using **Metal Alloy Powder** technology. This construction offers several advantages over traditional ferrite core inductors: * **Magnetic Shielding:** The molded construction minimizes electromagnetic interference (EMI), which is critical in dense PCB layouts like smartphones. * **Soft Saturation:** Unlike ferrite cores that lose inductance sharply when current limits are reached, the metal alloy core has a "soft" saturation curve, making the circuit more stable under peak loads. * **Miniaturization:** The 2012 footprint (0805 imperial equivalent) allows for high power density in extremely small spaces. --- ### 3. Common Applications This specific inductor (0.68 µH) is optimized for high-frequency switching regulators. * **Smartphones and Tablets:** Used in the PMIC (Power Management IC) stages to provide stable voltage to CPUs and GPUs. * **IoT Devices:** Ideal for small, battery-operated sensors requiring efficient power conversion. * **SSD Drives:** Used in the local power rails of solid-state storage. * **DC-DC Buck Converters:** Specifically for converters operating in the 1MHz to 5MHz range. --- ### 4.
