The **HC2-6R0-R** is a high-current, low-profile power inductor manufactured by Eaton (formerly Bussmann/Coiltronics). It is part of the HC2 series, designed specifically for high-density power conversion applications. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the HC2-6R0-R: | Parameter | Specification | | :--- | :--- | | **Inductance** | 6.0 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | 11.2 Amperes | | **Saturation Current (Isat)** | 12.0 Amperes | | **DC Resistance (DCR)** | 7.9 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | SMD (Surface Mount Device) | | **Dimensions** | ~ 13.5mm x 13.0mm x 6.0mm | --- ### 2. Key Features and Materials * **High Current Handling:** Designed to manage significant current with minimal power loss due to its low DC resistance (DCR). * **Magnetic Shielding:** The part is shielded, which reduces Electromagnetic Interference (EMI) and prevents the magnetic field from affecting neighboring components. * **Powder Iron Core:** It utilizes a high-frequency powder iron core material which provides a "soft" saturation characteristic (the inductance drops gradually rather than abruptly as current increases). * **RoHS Compliant:** The "-R" suffix indicates that the part is lead-free and complies with RoHS standards. --- ### 3. Common Applications The HC2-6R0-R is typically found in power management circuits where space is limited but power requirements are high: 1. **Voltage Regulator Modules (VRMs):** Used in CPU and GPU power delivery on motherboards. 2. **DC-DC Converters:** Buck, Boost, and SEPIC converters in industrial or computing hardware. 3. **Distributed Power Systems:** Managing power rails in telecommunications equipment. 4. **Battery Powered Systems:** High-efficiency power conversion for mobile or portable devices. --- ### 4.
