The **UP2UC-1R0-R** is a specific surface-mount power inductor manufactured by **Eaton (formerly Cooper Bussmann)**. It belongs to the Uni-Pac (UP) series, which is known for its high power density and reliability in DC-DC converter applications. --- ### 1. Key Specifications The technical attributes of the UP2UC-1R0-R are summarized in the table below: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 1.0 µH (Microhenry) | | **Tolerance** | ±20% | | **Current Rating (rms)** | 7.3 Amperes | | **Saturation Current (Isat)** | 11.2 Amperes | | **DC Resistance (DCR)** | 8.2 mΩ (Max) | | **Package / Case** | UP2UC (Surface Mount) | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Core Features * **High Energy Storage:** Designed for high-frequency applications where high current handling is required in a small footprint. * **Magnetic Shielding:** While some inductors in this class are unshielded, the UP2UC series utilizes a drum core construction that balances cost and EMI performance. * **Robust Construction:** The "R" suffix indicates that the part is **RoHS compliant**, meaning it is free from hazardous substances like lead. * **Material:** It typically uses a ferrite core, providing low core losses at high frequencies. --- ### 3. Application Use Cases This component is primarily used in power management circuits. Common applications include: 1. **Buck/Boost Converters:** Stepping voltage up or down in battery-powered devices. 2. **Computer Peripherals:** Voltage Regulation Modules (VRMs) for CPUs and GPUs. 3. **Industrial Electronics:** Distributed power systems and DC-DC modules. 4. **Telecommunications:** Used in base stations and networking hardware for filtering and energy storage. --- ### 4. Part Number Breakdown Understanding the nomenclature helps in identifying similar parts: * **UP2UC:** The series name and physical package size. * **1R0:** The inductance value. The "R" acts as a decimal point ($1.0$). If it were $100$, it would mean $10$ µH. * **R:** Indicates RoHS compliance.
