The **HC8LP-R15-R** is a high-current, low-profile power inductor manufactured by Eaton (formerly Bussmann). It is part of the HC8LP series, specifically designed for high-density power conversion applications. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the HC8LP-R15-R: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.15 µH | | **Tolerance** | ±20% | | **Rated Current (Irms)** | 35.0 Amperes | | **Saturation Current (Isat)** | 52.0 Amperes | | **DC Resistance (DCR)** | 0.55 mΩ (Max) | | **Operating Temperature** | -40°C to +125°C | | **Form Factor** | Low Profile (Surface Mount) | | **Dimensions** | ~10.9mm x 10.4mm x 4.0mm | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the component's specific traits: * **HC8LP**: The series name (High Current, Low Profile). * **R15**: Represents the inductance value. "R" acts as a decimal point ($0.15$ µH). * **R**: Indicates that the product is RoHS compliant. --- ### 3. Key Features & Materials * **High Current Density:** Capable of handling very high peak currents (up to 52A saturation) without significant inductance drop. * **Low DCR:** The extremely low DC resistance (0.55 mΩ) minimizes power loss due to heat, significantly increasing efficiency. * **Magnetic Shielding:** It is designed with a powdered iron core material that provides natural shielding, reducing Electromagnetic Interference (EMI) with surrounding components. * **Construction:** It features a flat-wire design which allows for a larger surface area, reducing the "skin effect" at high frequencies. --- ### 4. Common Applications This inductor is typically found in high-performance electronics where space is limited but power requirements are high: 1. **Voltage Regulator Modules (VRM):** Used in motherboards and servers to regulate CPU/GPU power. 2. **DC-DC Converters:** Buck, boost, and forward converters. 3. **Telecom/Datacom:** High-current power supplies for networking equipment. 4. **Distributed Power Systems:** Point-of-Load (POL) regulation.
