The **AISC-1210-R15** is a high-current, surface-mount (SMD) power inductor commonly used in DC-DC converters, voltage regulator modules (VRMs), and high-frequency power supplies. It belongs to the category of **molded power inductors**, known for their compact size and high efficiency. --- ### 1. Technical Specifications The part number follows a specific nomenclature where "1210" refers to the physical footprint and "R15" refers to the inductance value. | Feature | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.15 µH (R15) | | **Tolerance** | ±20% (M) | | **Dimensions** | Approx. 12.0 x 10.0 x 4.0 mm | | **Core Material** | Carbonyl Powder / Metal Alloy | | **Operating Temperature** | -40°C to +125°C | | **DC Resistance (DCR)** | Extremely Low (typically < 1.0 mΩ) | --- ### 2. Key Characteristics #### High Saturation Current ($I_{sat}$) Due to the metal alloy powder core, this inductor can handle very high peak currents without the inductance dropping off sharply. This is critical for preventing circuit failure during power spikes. #### Shielded Construction The "molded" design acts as a natural magnetic shield. This minimizes **Electromagnetic Interference (EMI)**, ensuring that the high-frequency switching noise doesn't interfere with nearby sensitive components on the PCB. #### Low DCR (Direct Current Resistance) The use of heavy-gauge flat wire or optimized copper windings results in ultra-low resistance. This minimizes power loss as heat ($P = I^2R$), leading to higher overall energy efficiency in the power circuit. --- ### 3. Common Applications This specific value (0.15 µH) is tailored for high-speed switching environments: * **Computing:** CPU and GPU core power supplies (Vcore). * **Networking:** High-speed routers and data center switches. * **Automotive:** ADAS systems and infotainment power management. * **DC-DC Converters:** Point-of-Load (POL) converters where high current and low profile are required. --- ### 4.
