The **LPS5030** series is a high-performance, low-profile, shielded power inductor manufactured by **Coilcraft**. It is widely used in compact electronic devices where board space and height are critical constraints. --- ## 1. Key Specifications The LPS5030 series is characterized by its square footprint and low vertical profile. Below are the general specifications for this series: | Property | Value/Range | | :--- | :--- | | **Footprint** | 5.0 mm x 5.0 mm | | **Height** | 3.0 mm (Max) | | **Inductance Range** | 0.90 µH to 4700 µH | | **Current (Irms)** | Up to 4.2 Amps | | **Shielding** | Magnetically Shielded | | **Core Material** | Ferrite | --- ## 2. Technical Features ### Magnetic Shielding The inductor is magnetically shielded, which significantly reduces **Electromagnetic Interference (EMI)**. This makes it ideal for high-density circuits where components are placed close together, preventing the inductor's magnetic field from interfering with sensitive nearby traces. ### Low Profile With a maximum height of only **3.0 mm**, the LPS5030 is designed for ultra-thin electronics like smartphones, tablets, and portable medical devices. ### DCR (DC Resistance) The series is engineered to have a low DCR, which minimizes power loss (heat) and improves the overall efficiency of the power converter. --- ## 3. Common Applications Due to its robust performance and small size, the LPS5030 is typically found in: * **DC-DC Converters:** Buck, Boost, and SEPIC topologies. * **Handheld Devices:** Mobile phones and GPS units. * **LCD Displays:** Backlighting drivers and bias supplies. * **Battery Powered Equipment:** Where high efficiency is required to extend battery life. --- ## 4.
