Technical Specifications The following table outlines the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Inductance** | 0.36 µH | | **Tolerance** | ±20% | | **Rated Current (Irms)** | 35 Amps | | **Saturation Current (Isat)** | 60 Amps | | **DC Resistance (DCR)** | 1.1 mΩ (typical) / 1.3 mΩ (max) | | **Operating Temperature** | -40°C to +150°C | | **Package Dimensions** | 11.5 x 10.0 x 3.8 mm | --- ### 2. Key Features and Construction * **Shielded Construction:** The part uses a carbonyl powder core. This design minimizes electromagnetic interference (EMI) and provides a low magnetic flux leakage. * **High Saturation Current:** Because of the metal alloy core material, the inductor exhibits a "soft" saturation characteristic, allowing it to handle high peak currents without a sudden drop in inductance. * **Low DCR:** The use of flat wire or heavy-gauge copper winding ensures extremely low direct current resistance, which minimizes power loss and heat generation. * **AEC-Q200 Compliance:** This series is typically automotive grade, meaning it can withstand high vibration and thermal shock. --- ### 3. Applications The SRP1040-R36M is commonly found in circuits requiring high efficiency and compact size: 1. **DC/DC Converters:** Used as the main energy storage element in buck/boost regulators. 2. **GPU/CPU Power:** Providing stable current to high-performance processors in laptops and servers. 3. **Automotive Systems:** Found in infotainment, driver assistance systems (ADAS), and lighting. 4. **Battery Powered Devices:** Ideal for high-current power banks and portable industrial tools. --- ### 4.
