Typical Applications & Why This Part Fits

• RF Impedance Matching: The tight 12nH tolerance and high self-resonant frequency make it ideal for antenna matching circuits where consistent reactance is critical.
• DC-DC Filtering: With a 400mA current handling and 400 mOhm DCR, it effectively smooths ripple in low-power portable device power rails without excessive loss.
• High-Frequency Signal Paths: muRata’s multilayer construction ensures minimal parasitic capacitance, preserving signal integrity in 2.4 GHz ISM band modules.

Key Features & Advantages

• Precision 12nH ±5%: Guarantees repeatable inductor behavior for sensitive RF front-end designs, reducing tuning effort.
• 400mOhm DCR at 400mA: Balances low resistive loss with adequate current margin, extending battery life in IoT devices.
• SMD 0402 Footprint: Ultra-compact package (1.0×0.5×0.5mm) frees PCB space for additional components in miniaturized wearables.
