### HCE-13-R: High Current Inductor (Automotive Grade) The **HCE-13-R** is a high-current, surface-mount power inductor typically manufactured by **Eaton (formerly Bussmann/Coiltronics)**. It is part of the HCE (High Current Edge-wound) series, designed for high-power density applications where low resistance and high reliability are critical. --- ### 1. Key Technical Specifications The following table summarizes the typical electrical and physical characteristics of the HCE-13 series: | Parameter | Specification | | :--- | :--- | | **Inductance Range** | 0.22 µH to 2.2 µH (Typical) | | **Current Rating ($I_{rms}$)** | Up to 60A+ (Size dependent) | | **Saturation Current ($I_{sat}$)** | High (designed for minimal drop-off) | | **DCR (DC Resistance)** | Ultra-low (mΩ range) | | **Operating Temperature** | -40°C to +125°C or +155°C | | **Construction** | Edge-wound Flat Wire | | **Package Size** | 13mm x 13mm (approximate footprint) | --- ### 2. Core Features and Construction * **Edge-wound Technology:** Instead of standard round wire, this inductor uses a flat copper ribbon wound on its edge. This maximizes the cross-sectional area of the conductor, significantly reducing **DC Resistance (DCR)** and improving heat dissipation. * **Composite Core Material:** It utilizes a molded iron powder or alloy core. This provides "soft saturation" characteristics, meaning the inductance decreases gradually as current increases rather than dropping off sharply. * **EMI Shielding:** The molded construction provides inherent magnetic shielding, reducing Electromagnetic Interference (EMI) with neighboring components on the PCB. * **AEC-Q200 Compliance:** Most parts in this series are automotive-grade, making them suitable for harsh environments with high vibration and thermal cycling. --- ### 3. Common Applications The HCE-13-R is designed for high-efficiency power conversion in the following areas: 1. **Automotive Systems:** Integrated Starter Alternators (ISG), DC-DC converters for Electric Vehicles (EV), and ADAS power rails. 2. **Computing & Servers:** Voltage Regulator Modules (VRM) for high-performance CPUs and GPUs. 3. **Industrial:** High-current power supplies and motor control circuits. 4. **Telecommunications:** Distributed power architectures and base station power modules. --- ### 4. Part Number Breakdown The suffix "-R" generally denotes **RoHS Compliance**, indicating that the part is lead-free and meets environmental safety standards. ```text HCE - 13 - [Inductance Code] - R | | | | Series Size e.g., R22=0.22uH RoHS Compliant ``` ---
