Technical Specifications The following table highlights the core electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% | | **DC Resistance (DCR)** | 35 mΩ (Typ) / 42 mΩ (Max) | | **Saturation Current ($I_{sat}$)** | 4.8 A | | **Heating Current ($I_{rms}$)** | 3.5 A | | **Operating Temperature** | -40 °C to +125 °C | | **Package Size** | 3.2 x 3.0 x 1.0 mm (0310) | --- ### 2. Key Features and Construction The SRP0310F series is built using advanced materials to optimize efficiency in small footprints. * **Shielded Construction:** The inductor is magnetically shielded, which ensures low magnetic field radiation. This is critical for preventing Electromagnetic Interference (EMI) with neighboring components. * **Metal Alloy Powder Core:** Unlike traditional ferrite cores, the metal powder core offers a "soft saturation" characteristic. This means the inductance drops gradually as current increases, rather than dropping sharply. * **Low Profile:** With a maximum height of only 1.0 mm, it is ideal for ultra-thin portable electronics. * **Lead-Free/RoHS Compliant:** Meets modern environmental safety standards. --- ### 3. Applications and Usage This part is primarily used in DC-DC converters and power management modules. Common applications include: * **Mobile Devices:** Power rails for CPUs and GPUs in smartphones. * **Storage:** Voltage regulation in Solid State Drives (SSDs). * **Computing:** DC-DC converters for ultra-books and tablets. * **Distributed Power:** Point-of-Load (POL) converters where space is at a premium. --- ### 4.
