The **ASPI-7318-R10** is a high-current power inductor manufactured by Abracon. It belongs to the surface-mount (SMD) molded inductor category, designed primarily for power management applications. --- ### 1. General Specifications Below are the primary technical parameters for the ASPI-7318-R10: | Parameter | Specification | |:---|:---| | **Inductance** | 0.10 µH (100 nH) | | **Tolerance** | ±20% (M) | | **DC Resistance (DCR)** | ~0.65 mΩ (Typ) / 0.85 mΩ (Max) | | **Saturation Current (Isat)** | ~55.0 A | | **Temperature Rise Current (Irms)** | ~32.0 A | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | 7.3 x 6.6 x 3.0 mm | --- ### 2. Key Features and Construction * **Molded Structure:** The part features a metal powder molding technology. This provides a magnetic shield that reduces EMI (Electromagnetic Interference) and minimizes audible buzz. * **High Current Handling:** With a saturation current of 55A, it is capable of handling high peak currents without the magnetic core "saturating" (losing its inductive properties). * **Low DCR:** The extremely low DC resistance (measured in milliohms) ensures minimal power loss and heat generation, increasing overall circuit efficiency. --- ### 3. Common Applications This specific inductor is typically found in the following electronic circuits: * **DC/DC Converters:** Used in buck, boost, and SEPIC converters for voltage regulation. * **CPU/GPU Power:** High-current power rails for processors in laptops, servers, and workstations. * **Automotive Electronics:** Infotainment and lighting systems requiring stable power delivery. * **Battery Powered Devices:** Due to high efficiency and compact footprint. --- ### 4.
