The **PI07024-R47M** is a high-current, shielded power inductor typically used in DC-DC converter applications. It belongs to a category of surface-mount (SMD) components designed for high efficiency and low electromagnetic interference (EMI). --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics of the component: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **PI** | Series Code | Power Inductor (High Current Series) | | **07024** | Physical Size | Dimensions (approx. 7.0mm x 6.6mm x 2.4mm) | | **R47** | Inductance Value | 0.47 µH (Microhenries) | | **M** | Tolerance | ±20% | --- ### 2. Key Technical Specifications While specific data can vary slightly by manufacturer (such as Cyntec or Chilisin), the standard parameters for a 07024-R47M are generally as follows: * **Inductance:** 0.47 µH * **DC Resistance (DCR):** Extremely low (typically between 2.0mΩ to 4.5mΩ) to minimize power loss. * **Saturation Current (Isat):** The current at which inductance drops by ~30%. Usually ranges from **15A to 25A**. * **Rated Current (Irms):** The current that causes a 40°C temperature rise. Usually ranges from **12A to 20A**. * **Operating Temperature:** -40°C to +125°C (includes self-heating). --- ### 3. Core Features * **Magnetic Shielding:** The inductor is molded with a magnetic metal powder core, which reduces "stray" magnetic fields that could interfere with nearby components. * **Low Profile:** The "24" in the part number indicates a height of roughly 2.4mm, making it ideal for slim electronics like laptops or tablets. * **High Saturation:** Unlike ferrite drum cores, these metal composite cores have a "soft" saturation characteristic, meaning they don't lose inductance abruptly when current spikes. --- ### 4. Common Applications Due to its high current handling and small footprint, this part is found in: 1. **Voltage Regulator Modules (VRM):** Powering CPUs and GPUs in computing. 2. **Point of Load (POL) Converters:** Step-down (Buck) converters on motherboards. 3. **Battery Powered Devices:** High-efficiency power management for mobile devices. 4. **Automotive Electronics:** Infotainment and ADAS power rails (if AEC-Q200 qualified). --- ### 5. Equivalent Replacement Guide If you are looking for an alternative, ensure the footprint and height match. Common equivalent series include: * **Vishay:** IHLP-2525CZ-01 * **Bourns:** SRP7028 series * **TDK:** SPM6530 series
