The **HCP0704-R60-R** is a high-current, power inductor manufactured by Eaton (formerly Cooper Bussmann). It belongs to the HCP series, which is designed specifically for high-frequency voltage regulator modules (VRMs) and power supplies. ### 1. Key Specifications The following table outlines the technical parameters for this specific part number: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.60 µH (Microhenries) | | **Tolerance** | ±20% | | **Rated Current (Irms)** | 23.0 A | | **Saturation Current (Isat)** | 31.0 A | | **DC Resistance (DCR)** | 2.15 mΩ (Typical) | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | SMD (Surface Mount Device) | | **Dimensions** | 7.0mm x 6.4mm x 4.0mm | --- ### 2. Physical Construction and Materials The "HCP" designation stands for **High Current Power**. The construction details are critical for its performance: * **Core Material:** Iron powder or alloy powder technology. This provides a "soft" saturation characteristic, meaning the inductance doesn't drop off instantly as current increases. * **Shielding:** The component is magnetically shielded, which minimizes Electromagnetic Interference (EMI) with surrounding components on the PCB. * **Lead-Free:** It is fully RoHS compliant and uses lead-free finishes for soldering. --- ### 3. Application Use Cases This inductor is typically found in high-performance computing environments where high current needs to be delivered at low voltages. * **Voltage Regulator Modules (VRM):** Used in motherboards and servers to step down voltage for CPUs and GPUs. * **DC-DC Converters:** High-efficiency buck converters for telecommunications equipment. * **Distributed Power Systems:** Used in industrial power bricks and modules. * **Battery Powered Systems:** Where low DCR is required to maximize battery life by reducing heat loss ($P = I^2R$). --- ### 4. Part Number Breakdown Understanding the Eaton nomenclature: * **HCP:** Series Name (High Current Power). * **0704:** Physical Size (Approx. 7mm x 4mm height). * **R60:** Inductance value (R60 = 0.60 µH). * **-R:** RoHS compliant.
