The **HC6-R** is a high-performance, high-current power inductor series manufactured by **Eaton (formerly Cooper Bussmann)**. These components are specifically designed for demanding automotive and industrial applications where high reliability and efficiency are required. --- ### 1. Key Technical Specifications The HC6-R series is known for its low core loss and high current-handling capabilities. Below are the typical specifications found across the series: | Property | Typical Value / Range | | :--- | :--- | | **Inductance Range** | 0.22 µH to 22.0 µH | | **Current Rating (Irms)** | Up to 52 Amps | | **Peak Current (Isat)** | Up to 110 Amps | | **Operating Temperature** | -40°C to +125°C | | **Material** | Powder Iron Core (Organic Binder) | | **Frequency Range** | Up to 1 MHz | --- ### 2. Physical Construction and Parts The component is engineered with several distinct electronic and structural features: * **Core Material:** Uses a specialized iron powder core. This provides a "soft saturation" characteristic, meaning the inductance drops gradually as current increases rather than dropping off sharply. * **Windings:** Utilizes heavy-gauge copper wire to minimize **DCR** (Direct Current Resistance), which reduces heat generation and improves energy efficiency. * **Shielding:** The construction is inherently magnetically shielded due to the molded design, which minimizes EMI (Electromagnetic Interference) with surrounding components. * **Terminals:** Features robust SMT (Surface Mount Technology) pads designed to handle high vibration and thermal cycling. --- ### 3. Applications The HC6-R is primarily used in power conversion circuits. Common use cases include: 1. **Multi-phase Regulators:** Used in CPU/GPU power modules. 2. **Voltage Regulator Modules (VRMs):** For high-current point-of-load converters. 3. **Automotive Electronics:** Powering infotainment, ECU, and lighting systems (often AEC-Q200 compliant variants). 4. **Industrial Inverters:** DC-to-DC converters for heavy machinery. --- ### 4. Part Numbering Example When sourcing this part, the suffix often indicates the specific inductance value: `HC6-1R0-R` * **HC6:** Series Identifier. * **1R0:** Inductance value (1.0 µH). * **-R:** RoHS compliant (Lead-free).
