The **VP5-0053-R** is a high-performance power inductor manufactured by **Eaton (formerly Coiltronics)**. It belongs to the Versa-Pac series, which is known for its multi-winding flexibility. --- ## 1. Core Technical Specifications The VP5-0053-R is designed as a surface-mount (SMD) component featuring six identical windings. This allows for various configurations including step-up, step-down, coupled, or isolated transformers. | Feature | Specification | | :--- | :--- | | **Series** | Versa-Pac (VP5) | | **Number of Windings** | 6 | | **Inductance (per winding)** | 9.0 µH | | **Rated Current (per winding)** | 1.80 A | | **DC Resistance (Max)** | 0.046 Ω | | **Operating Temperature** | -40°C to +125°C | | **Mounting Type** | Surface Mount (SMD) | | **RoHS Compliant** | Yes (indicated by the "-R" suffix) | --- ## 2. Key Electronic Features ### Multi-Winding Versatility The most distinct feature of the VP5-0053-R is the **six separate windings**. By connecting these windings in series or parallel, engineers can drastically change the component's characteristics: * **Series Connection:** Increases total inductance and voltage rating. * **Parallel Connection:** Increases total current carrying capacity. ### Low EMI Design The component uses a **toroidal core geometry**. Because the magnetic flux is contained within the circular core, it produces very low electromagnetic interference (EMI), making it ideal for sensitive electronic circuits. ### High Power Density Despite its small footprint, it provides high energy storage capability, which is essential for compact power supplies in telecommunications and industrial equipment. --- ## 3. Common Applications Due to its flexible nature, the VP5-0053-R is used in various power conversion topologies: * **DC-DC Converters:** Specifically Buck, Boost, and SEPIC converters. * **Isolation:** Used as a 1:1 or multi-ratio isolation transformer. * **Filters:** Utilized in differential mode or common mode filtering to reduce noise. * **Voltage Doublers:** Taking advantage of the multiple taps to create higher voltage rails. --- ## 4. Typical Footprint and Geometry The VP5 series utilizes a specific "Size 5" package. ```text Approximate Dimensions: - Length: 13.0 mm - Width: 13.0 mm - Height: 6.35 mm (Max) ```
