Typical Applications & Why This Part Fits

• DC-DC Converter Output Filters: The 2.2µH value and 700mA current rating make it ideal for buck converters in mobile devices, where stable output voltage with low ripple is required.
• Power Line Noise Suppression: A DCR of 470mΩ helps limit power loss while still attenuating high-frequency noise, suitable for mixed-signal circuits in IoT sensors.
• Wearable Battery Management: The compact SMD footprint and 700mA capability allow it to fit into smartwatch power paths without sagging under peak loads.

Key Features & Advantages

• Precise 2.2µH Inductance: Provides tight tolerance for consistent filtering in regulated power rails, minimizing voltage overshoot.
• 700mA Current Handling: Supports moderate load demands typical of portable electronics, ensuring reliable operation without magnetic saturation.
• Low 470mΩ DCR: Reduces I²R losses and self-heating, improving overall efficiency in continuous-duty applications.
