The **47LCT-161R-R** is a specific electronic component typically identified as a **High-Current Power Inductor** (Surface Mount Device - SMD). These components are essential in power management circuits for energy storage and filtering. --- ### 1. Technical Specifications While specifications can vary slightly by manufacturer (often associated with brands like **Mag Layers** or **Coilmaster**), the part number breaks down into the following typical characteristics: | Parameter | Typical Value / Description | | :--- | :--- | | **Inductance** | 0.16 µH (indicated by "161") | | **Tolerance** | ±20% (Common for "R" or "M" suffixes) | | **Type** | Shielded Power Inductor | | **Mounting Type** | SMD/SMT (Surface Mount Technology) | | **Material** | Metal Alloy / Carbonyl Powder Core | ### 2. Physical Characteristics * **Form Factor:** Low profile, compact square or rectangular footprint. * **Shielding:** Magnetically shielded construction to minimize Electromagnetic Interference (EMI) with surrounding components. * **Construction:** Molded body which provides high mechanical pressure resistance and minimizes "acoustic noise" (buzzing). ### 3. Key Features * **High Saturation Current:** Designed to handle high peak currents without the inductance dropping significantly. * **Low DC Resistance (DCR):** Uses flat wire or thick copper windings to minimize power loss and heat generation. * **Frequency Range:** Optimized for high-frequency DC-DC converters (switching power supplies). ### 4. Typical Applications The 47LCT-161R-R is commonly found in the following electronic assemblies: 1. **Voltage Regulator Modules (VRM):** Used in motherboards and GPU power phases. 2. **DC-DC Converters:** Point-of-load (POL) converters for telecommunications. 3. **Laptop/Tablet Power:** High-efficiency power rails for CPUs and chipsets. 4. **Automotive Electronics:** Power filtering for infotainment or ADAS systems. --- ### Internal Wiring Diagram (Conceptual) ```text [Terminal 1] ----( Coil )---- [Terminal 2] | [Shielded Housing] ```
