Typical Applications & Why This Part Fits

• Portable Device Power Rails: The 1.2A current rating and 2.2µH inductance are ideal for small buck converters in smartphones or wearables, where PCB real estate is scarce but ripple suppression is critical.
• Module Input/Output Filtering: Its 138mΩ DCR minimizes I²R losses, making it suitable for efficiently filtering noise at the input of RF modules or sensor arrays.
• Low-Profile IoT Endpoints: muRata’s construction ensures reliable performance under temperature fluctuations, crucial for battery-operated IoT nodes demanding consistent 2.2µH tolerance.

Key Features & Advantages

• 2.2µH ±20% Inductance: Balanced for mid-frequency switching (2-4 MHz), delivering stable current ripple without oversaturating the core at full load.
• 1.2A Saturation Current: Handles peak transients in power-gating scenarios without hard saturation, preserving efficiency across load steps.
• 138mΩ Max DCR: Low DC resistance reduces heat generation—critical for dense SMD layouts where thermal dissipation is limited.
