Typical Applications & Why This Part Fits

• RF Blocking & Impedance Matching: The 220nH inductance at 120mA capacity suits narrowband filters and antenna matching in IoT modules, where the 3.77Ω DCR ensures minimal signal attenuation.
• DC-DC Converter Noise Suppression: In low-power buck converters for wearables, its compact SMD footprint and stable inductance over temperature help suppress high-frequency ripple without exceeding current limits.
• Signal Line Choking: For I²C or SPI data lines in sensor nodes, the 220nH value paired with 120mA rating provides effective common-mode noise filtering while keeping DC resistance low enough to avoid voltage drops.

Key Features & Advantages

• Precision Inductance at 220nH ±5%: Murata multilayer construction delivers tight tolerance, ensuring consistent performance across production batches for resonant circuits.
• Low DCR of 3.77Ω Saves Power: Minimal resistive losses extend battery life in portable devices, especially during continuous 120mA operation.
• SMD Package for High-Density Assembly: The miniaturized SMD body allows placement in dense PCB layouts common in Bluetooth modules and NFC tags.
