The **ASPI-2012-R16** is a specific surface-mount power inductor manufactured by Abracon. It belongs to the **ASPI-2012** series, which is designed for high-density applications where space is limited and power efficiency is critical. --- ## 1. Technical Specifications The following table highlights the primary electrical and physical characteristics of the **R16** variant: | Parameter | Value | Notes | | :--- | :--- | :--- | | **Inductance** | 0.16 µH | The "R16" in the part number signifies 0.16 | | **Tolerance** | ±20% (M) or ±30% (N) | Typical variance for power inductors | | **DC Resistance (DCR)** | ~11 mΩ | Max resistance to direct current | | **Saturation Current ($I_{sat}$)** | ~5.8 A | Current at which inductance drops by 30% | | **RMS Current ($I_{rms}$)** | ~4.5 A | Current based on a 40°C temperature rise | | **Case Size** | 2012 (Metric) | 2.0mm x 1.25mm x 1.0mm (approx.) | --- ## 2. Key Features & Construction The ASPI-2012 series utilizes specific materials and designs to achieve its performance: * **Metal Alloy Construction:** Unlike traditional ferrite inductors, these use a metal alloy powder core. This allows for higher saturation currents and a "soft" saturation curve (meaning it doesn't lose efficiency instantly when current spikes). * **Magnetically Shielded:** The design minimizes Electromagnetic Interference (EMI), preventing the inductor from interfering with nearby sensitive components on the PCB. * **Low Profile:** The "2012" footprint is roughly equivalent to a 0805 Imperial size, making it extremely thin (1.0mm max height), ideal for smartphones and wearables. --- ## 3. Common Applications Due to its high current handling and small size, the ASPI-2012-R16 is typically found in: 1. **DC-DC Converters:** Specifically Point-of-Load (PoL) modules for CPUs and GPUs. 2. **Mobile Devices:** Power management circuits in smartphones, tablets, and smartwatches. 3. **Portable Electronics:** Battery-powered devices requiring high efficiency to extend battery life. --- ## 4.
