## SD7030-560-R Electronic Component Overview The **SD7030-560-R** is a high-performance, shielded power inductor manufactured by **Eaton (formerly Bussmann)**. It belongs to the SD7030 series, which is designed for applications requiring high power density and low electromagnetic interference (EMI). --- ### 1. Key Specifications The following table summarizes the technical parameters of the SD7030-560-R: | Parameter | Value | Notes | | :--- | :--- | :--- | | **Inductance** | 56 $\mu$H | Measured at 100 kHz, 0.25 Vrms | | **Tolerance** | ±20% | Standard manufacturing variance | | **DC Resistance (DCR)** | 0.170 $\Omega$ | Typical resistance at 20°C | | **Rated Current ($I_{rms}$)** | 1.17 A | Based on 40°C temperature rise | | **Saturation Current ($I_{sat}$)** | 1.12 A | Based on 30% drop in inductance | | **Shielding** | Yes | Magnetically shielded for low EMI | | **Package / Case** | 7.0mm x 7.0mm x 3.0mm | Surface Mount (SMD) | --- ### 2. Component Construction & Design * **Magnetic Shielding:** The part features a ferrite core and a ferrite sleeve. This "shielded" construction confines the magnetic flux within the component, preventing interference with neighboring sensitive circuits (crucial for high-density PCBs). * **Material:** It uses a ferrite core material known for low core losses, making it efficient for high-frequency switching. * **Termination:** The pads are typically matte tin over copper, ensuring excellent solderability for SMT (Surface Mount Technology) processes. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying variants: | Segment | Meaning | | :--- | :--- | | **SD** | Series name (Shielded Drum) | | **7030** | Dimensions (approx. 7.0mm width/length, 3.0mm height) | | **560** | Inductance code ($56 \times 10^0 = 56\mu$H) | | **-R** | RoHS compliant / Lead-free | --- ### 4.
