The **ASPI-2510-R47** is a surface-mount (SMD) power inductor commonly used in DC-DC converters and power management circuits. It is manufactured by **Abracon** and is known for its compact profile and efficiency. --- ## 1. Technical Specifications The part number "R47" specifically identifies the inductance value. Below are the primary electrical and physical characteristics: | Property | Value | | :--- | :--- | | **Inductance** | 0.47 µH | | **Tolerance** | ±30% (Standard for this series) | | **DC Resistance (DCR)** | ~33 mΩ (Max) | | **Saturation Current (Isat)** | ~3.15 A | | **Temperature Rise Current (Irms)** | ~2.50 A | | **Package Size** | 2.5 x 2.0 x 1.0 mm | | **Operating Temperature** | -40°C to +125°C | --- ## 2. Key Features * **Low Profile:** The "10" in the part number indicates a maximum height of 1.0 mm, making it ideal for ultra-thin electronics like smartphones and tablets. * **Magnetic Shielding:** The inductor is magnetically shielded to reduce Electromagnetic Interference (EMI), which is critical in dense PCB layouts. * **High Current Handling:** Despite its small footprint, it can handle relatively high saturation currents due to its specialized core material. * **Wire-Wound Construction:** This provides lower DC resistance compared to multilayer inductors of the same size. --- ## 3. Typical Applications The ASPI-2510 series is designed for power-hungry, space-constrained devices: * **Mobile Devices:** Smartphones, tablets, and wearables. * **Computing:** SSDs (Solid State Drives) and portable hard drives. * **DC/DC Converters:** Point-of-Load (POL) modules for voltage regulation. * **IoT:** Small sensors and battery-powered modules. --- ## 4.
