It is designed for high-density power applications where low DC resistance and high saturation currents are required. --- ### 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.33 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | 26.0 Amperes | | **Saturation Current (Isat)** | 44.0 Amperes | | **DC Resistance (DCR)** | 1.8 mΩ (Max) | | **Operating Temperature** | -55°C to +150°C | | **Package / Case** | 7.30mm x 6.60mm x 3.0mm | | **Construction** | Metal Alloy Powder Core | --- ### 2. Key Features * **Magnetic Shielding:** The inductor is magnetically shielded, which minimizes electromagnetic interference (EMI) with surrounding components. * **High Saturation Current:** The iron powder core allows for a "soft" saturation profile, meaning the inductance drops gradually rather than abruptly when current limits are exceeded. * **AEC-Q200 Compliance:** This specific series is often qualified for automotive use, ensuring high reliability under thermal shock and vibration. * **Low DCR:** The use of flat wire or specialized winding techniques minimizes power loss through heat (Joule heating). --- ### 3. Common Applications Due to its high current handling and compact size, the SRP7030-R33FM is typically found in: 1. **DC/DC Converters:** Used as a storage inductor in buck, boost, and SEPIC topologies. 2. **Power Supplies for GPUs/CPUs:** Ideal for Voltage Regulator Modules (VRMs) requiring high transient currents. 3. **Automotive Electronics:** Used in infotainment, lighting, and ADAS systems. 4. **Consumer Electronics:** High-end laptops and gaming consoles. --- ### 4. Footprint and Soldering The component uses an **SMD (Surface Mount Device)** footprint. The "7030" in the part number refers to the approximate dimensions: * **7.0 mm** length/width. * **3.0 mm** height. ```text Recommended Pad Layout (Approx): [ 3.5mm ] <-- Pad Width [ 1.5mm ] <-- Pad Length [ 2.5mm ] <-- Space between pads ```
