Key Specifications The following table outlines the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.47 µH | | **Tolerance** | ±20% (indicated by 'M') | | **Inductance Code** | R47 | | **DC Resistance (DCR)** | ~0.015 Ω (Max) | | **Saturation Current (Isat)** | ~4.5 A to 5.5 A | | **Operating Temperature** | -40°C to +125°C | | **Package Type** | Shielded Surface Mount (SMD) | | **Core Material** | Iron Powder / Metal Alloy | --- ### 2. Breakdown of the Part Number To understand the specific features of this component, we can deconstruct the naming convention: * **AIAM**: Series identifier (Molded Power Inductor series). * **02**: Physical size/dimension code (Small footprint for high-density PCBs). * **R47**: Inductance value ($0.47 \mu H$). The 'R' acts as a decimal point. * **M**: Tolerance rating ($M = \pm 20\%$). --- ### 3. Features and Benefits The AIAM-02-R47M is engineered for modern high-frequency power electronics: * **Magnetically Shielded:** The molded construction minimizes electromagnetic interference (EMI), protecting nearby sensitive components. * **High Saturation:** Unlike ferrite inductors, the metal alloy core provides a "soft" saturation curve, allowing it to handle high current peaks without a sharp drop in inductance. * **Low DCR:** Reduces power loss and heat generation, which is critical for extending battery life in portable devices. * **AEC-Q200 Qualified (Often):** Most parts in this series are designed to meet automotive reliability standards. --- ### 4. Typical Applications This component is commonly found in the following circuits: * **DC/DC Converters:** Used as an energy storage element in buck, boost, and buck-boost regulators. * **Mobile Devices:** Power management in smartphones, tablets, and wearables. * **Embedded Systems:** Microprocessor and FPGA power supplies. * **Automotive Electronics:** Infotainment systems and ADAS sensors. --- ### 5. Implementation Example In a typical Buck Converter circuit, the inductor is placed at the output stage to smooth out the current. ```c // Example Calculation: Voltage Ripple // V_ripple = L * (di / dt) // Where: // L = 0.47uH (AIAM-02-R47M) // di = Change in current // dt = Switching period ``` ---
