The **SCIHP0750-R82** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converters and high-current power supplies. It belongs to the "molded" inductor category, designed to handle high saturation currents in a compact footprint. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify its physical and electrical characteristics: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **SCIHP** | Series Prefix | High-current, shielded molded power inductor series. | | **0750** | Dimensions | Approx. **7.0 x 7.5 mm** footprint; **5.0 mm** height. | | **R82** | Inductance | **0.82 µH** (R denotes the decimal point). | --- ### 2. Key Electrical Specifications Below are the typical technical parameters for this specific component: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.82 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | ~3.0 - 4.5 mΩ (Max) | | **Saturation Current (Isat)** | ~25 - 30 Amperes | | **Heating Current (Irms)** | ~15 - 20 Amperes | | **Operating Temperature** | -55°C to +125°C | --- ### 3. Core Features & Technology * **Molded Construction:** The coil is embedded in a magnetic metal powder iron core. This design eliminates the "air gap" found in traditional ferrite cores, resulting in a **soft saturation** characteristic (the inductance drops gradually rather than abruptly under high load). * **Magnetic Shielding:** The molded body acts as a natural shield, minimizing Electromagnetic Interference (EMI) and leakage flux. * **Low DCR:** The use of flat wire or heavy-gauge copper inside minimizes power loss and heat generation. * **Acoustic Quietness:** Because the structure is solid-molded, it is less prone to "coil whine" (magnetostriction) compared to traditional drum core inductors. --- ### 4. Typical Applications The SCIHP0750-R82 is ideal for high-density power electronics where space is limited but current demands are high: * **Voltage Regulator Modules (VRM):** For CPUs and GPUs in laptops and servers. * **DC-DC Converters:** Point-of-Load (POL) converters in telecommunications. * **Battery Powered Devices:** High-efficiency power management for portable tools. * **Automotive:** Infotainment and LED lighting drivers (if AEC-Q200 qualified). ---
