### ASPI-2010-R68 Electronic Component Overview The **ASPI-2010-R68** is a high-performance, surface-mount (SMD) power inductor. It is part of the ASPI-2010 series produced by Abracon, designed primarily for DC-DC conversion and power management in space-constrained electronics. --- ### 1. Key Technical Specifications The part number itself contains encoded information about its electrical characteristics. | Parameter | Value / Description | | :--- | :--- | | **Inductance** | 0.68 µH (indicated by "R68") | | **Tolerance** | ±20% (Standard for this series) | | **Case Size** | 2.0 x 1.6 x 1.0 mm | | **DC Resistance (DCR)** | ~45 mΩ (Max) | | **Saturation Current (Isat)** | ~3.3 A | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Physical Construction The ASPI-2010 series utilizes a **metal alloy powder core** construction. This provides several advantages over traditional ferrite inductors: * **Shielded Design:** The molded construction naturally reduces Electromagnetic Interference (EMI), making it suitable for high-density PCB layouts. * **Soft Saturation:** Unlike ferrite cores that drop inductance sharply when current limits are exceeded, this metal alloy core exhibits a "soft" saturation curve. * **Compact Footprint:** The "2010" designation refers to its metric dimensions (approximately 2.0mm by 1.6mm), allowing it to fit into mobile devices and wearables. --- ### 3. Applications and Usage This component is typically found in the power stage of portable electronic devices. * **DC-DC Converters:** Used in Buck (Step-down) or Boost (Step-up) converters to store energy. * **Mobile Devices:** Ideal for smartphones, tablets, and smartwatches due to its low profile (1.0mm height). * **Battery Powered Systems:** High efficiency and low DCR help prolong battery life. --- ### 4. Part Number Breakdown Understanding the nomenclature helps in selecting substitutes or variations: 1. **ASPI:** Abracon Surface Power Inductor Series. 2. **2010:** Dimensions (2.0mm length x 1.6mm width). 3. **R68:** Inductance value (R denotes the decimal point; 0.68 microhenries). ---
