The **ASPI-0706HC-R47** is a high-current, surface-mount (SMD) power inductor. It is designed for high-density power applications where space is limited and high efficiency is required. ### 1. Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Inductance** | 0.47 µH | | **Tolerance** | ±20% (M) | | **DC Resistance (DCR)** | ~0.0035 Ω (3.5 mΩ) Max | | **Saturation Current (Isat)** | ~25.0 A | | **Heat Rating Current (Irms)** | ~18.0 A | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | 7.30mm x 6.60mm x 3.00mm (Approx) | --- ### 2. Core Features & Construction * **High Current Handling:** The "HC" in the part number stands for **High Current**. It utilizes a molded metal powder core construction, which allows for high saturation currents and low DC resistance. * **Soft Saturation:** Unlike ferrite inductors that drop inductance sharply when current limits are exceeded, this part features a "soft saturation" characteristic. * **Magnetically Shielded:** The molded construction provides inherent magnetic shielding, reducing Electromagnetic Interference (EMI) with surrounding components on the PCB. * **Low Profile:** With a height of roughly 3.0mm, it is suitable for thin electronic devices like laptops or low-profile power modules. --- ### 3. Part Number Breakdown The nomenclature typically follows this logic: 1. **ASPI:** Abracon Surface Power Inductor series. 2. **0706:** Indicates the physical dimensions (approx. 7mm x 6mm footprint). 3. **HC:** High Current capability designation. 4. **R47:** Inductance value code (R denotes the decimal point; R47 = 0.47 µH). --- ### 4. Typical Applications * **DC/DC Converters:** Used in Buck, Boost, and SEPIC topologies. * **Voltage Regulator Modules (VRM):** Powering CPUs and GPUs in computing hardware. * **Battery Powered Devices:** High efficiency due to low DCR helps extend battery life. * **Automotive/Industrial:** Used in power distribution for sensors and control units.
