The **SCIHP0750-R68** is a high-current, surface-mount (SMD) power inductor commonly used in DC-DC converters and power supply modules. It belongs to the "molded" or "composite" inductor category, designed for high efficiency and low electromagnetic interference (EMI). --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify its physical and electrical characteristics: | Component Code | Description | Value/Detail | | :--- | :--- | :--- | | **SCIHP** | Series Name | High current, shielded power inductor | | **0750** | Size Code | Approx. 7.5mm x 7.0mm (Footprint) x 5.0mm (Height) | | **R68** | Inductance Value | 0.68 µH (Microhenries) | --- ### 2. Technical Specifications Below are the typical electrical parameters for this specific component: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR) Max** | ~2.5 mΩ to 4.5 mΩ (varies by manufacturer) | | **Saturation Current (Isat)** | ~25A to 30A (current at which inductance drops) | | **Heat Rating Current (Irms)** | ~18A to 22A (current causing 40°C temp rise) | | **Operating Temperature** | -55°C to +125°C | --- ### 3. Key Features * **Shielded Construction:** The magnetic metal powder core provides inherent shielding, which reduces EMI leakage that could interfere with nearby components. * **High Saturation:** Unlike traditional ferrite inductors, these molded types have a "soft" saturation characteristic, meaning they don't lose inductance abruptly when current spikes. * **Low DCR:** It uses heavy-gauge copper wire to minimize power loss through heat (Ohmic loss). * **Compact Design:** The 0750 size offers a high power-to-size ratio, ideal for modern, slim electronics. ### 4. Common Applications This inductor is typically found in high-demand power circuits: * **Voltage Regulator Modules (VRM):** For CPUs and GPUs in laptops or servers. * **DC/DC Converters:** Point-of-load (POL) converters. * **Battery Powered Systems:** High-efficiency power management for portable devices. * **Automotive:** Infotainment and LED lighting drivers (if AEC-Q200 qualified). ---
