Technical Specifications Below are the core electrical and physical parameters for the AMPLH5030S-R36M: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.36 µH | | **Tolerance** | ±20% (M) | | **DCR (Direct Current Resistance)** | ~2.5 mΩ (Nominal) | | **Saturation Current (Isat)** | ~18A - 22A (Depending on temperature rise) | | **Dimensions (LxWxH)** | 5.4mm x 5.2mm x 3.0mm (Approximate) | | **Operating Temperature** | -40°C to +125°C | | **Shielding** | Magnetically Shielded | --- ## 2. Part Number Breakdown Understanding the nomenclature helps in identifying the component's capabilities: * **AMPLH**: Series designation (likely High Current / Low Profile Molded Inductor). * **5030**: Package size (approx. 5.0mm x 5.0mm footprint, 3.0mm height). * **S**: Construction style (often refers to Shielded or Standard). * **R36**: Inductance value (R represents the decimal; 0.36 microhenries). * **M**: Tolerance code (M = ±20%). --- ## 3. Key Features ### High Current Handling The "Molded" construction uses a metal alloy powder. This allows the inductor to handle high saturation currents without a sharp drop in inductance, unlike traditional ferrite core inductors. ### Low DCR With a very low Direct Current Resistance, this part minimizes power loss through heat, making it highly efficient for battery-powered or high-performance electronics. ### Magnetic Shielding The molded body acts as a natural shield, significantly reducing Electromagnetic Interference (EMI) which is crucial for dense PCB layouts. --- ## 4. Typical Applications * **Computing:** CPU/GPU power supplies in laptops and servers. * **DC-DC Converters:** Buck, Boost, and Buck-Boost topologies. * **Mobile Devices:** High-efficiency power rails for smartphones and tablets. * **Automotive/Industrial:** Distributed power systems requiring compact, rugged components.
