The **AMPLH7020S-R68M** is a high-performance, shielded power inductor typically used in DC-DC converter circuits. It is designed for high-current applications where space and efficiency are critical. --- ### 1. Part Number Breakdown To understand the component, we can decode the nomenclature (based on standard industry naming for this series): | Segment | Meaning | Description | | :--- | :--- | :--- | | **AMPLH** | Series Type | High-current, molded power inductor series. | | **7020** | Case Size | Dimensions approx. 7.0mm x 6.6mm with a height of 2.0mm. | | **S** | Construction | Shielded construction (minimizes EMI). | | **R68** | Inductance | **0.68 µH** (R denotes the decimal point). | | **M** | Tolerance | **±20%** inductance tolerance. | --- ### 2. Key Technical Specifications While exact values can vary slightly by manufacturer (e.g., Cyntec or similar brands), the typical specs for a 7020 R68 inductor are: * **Inductance:** 0.68 µH * **DC Resistance (DCR):** Low (typically between 4mΩ to 6mΩ) to minimize power loss. * **Saturation Current ($I_{sat}$):** High (often ranging from 15A to 22A), meaning it maintains inductance even at high peak currents. * **Rated Current ($I_{rms}$):** High thermal current rating for continuous operation. * **Operating Temperature:** Typically -40°C to +125°C. --- ### 3. Core Features & Materials * **Metal Alloy Powder:** These inductors use a molded metal powder core. This provides "soft" saturation characteristics, meaning the inductance drops gradually rather than abruptly when current increases. * **Magnetic Shielding:** The molded construction naturally shields the component, reducing electromagnetic interference (EMI) with neighboring components on the PCB. * **Low Profile:** The "20" in the name indicates a 2.0mm height, making it ideal for thin electronic devices like laptops or tablets. --- ### 4. Typical Applications This specific inductor is commonly found in: 1. **Voltage Regulator Modules (VRMs):** Providing power to CPUs or GPUs. 2. **Point of Load (POL) Converters:** Used in telecommunications and networking gear. 3. **Battery Powered Devices:** High-efficiency DC-DC buck converters in smartphones and notebooks. 4. **Automotive Electronics:** If the specific sub-series is AEC-Q200 qualified.
