Technical Specifications Overview The alphanumeric code breaks down specific physical and electrical characteristics. Below is a breakdown of the typical parameters for this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Inductance** | 0.60 µH (derived from "60") | | **Tolerance** | ±20% (standard for power inductors) | | **Saturation Current ($I_{sat}$)** | High (designed for DC-DC converters) | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Operating Temperature** | -40°C to +125°C | | **Shielding** | Magnetically Shielded (reduces EMI) | --- ### 2. Part Number Breakdown While manufacturer naming conventions vary slightly, the string usually follows this logic: * **47L/LPQ**: Identifies the product series (Low Profile, High Q factor). "PQ" often refers to the core shape or specific power application. * **60**: Represents the inductance value. In this context, it usually signifies **0.60 microhenries (µH)**. * **YR**: Refers to the physical package size/dimensions (e.g., width and height in millimeters). * **R/Q**: * **R**: Often indicates the termination finish (e.g., RoHS compliant, Matte Tin). * **Q**: Typically denotes a specific quality grade (e.g., Automotive Grade AEC-Q200) or a specific packaging method (Tape & Reel). --- ### 3. Key Applications These inductors are engineered for efficiency in compact electronic environments: 1. **Voltage Regulator Modules (VRMs):** Used in CPU/GPU power delivery. 2. **Point-of-Load (POL) Converters:** Essential for stepping down voltage for microprocessors. 3. **Battery Powered Devices:** High efficiency helps extend battery life in laptops and tablets. 4. **Automotive Electronics:** If "Q" rated, it is used in infotainment or ADAS systems due to high thermal stability. --- ### 4.
