Typical Applications & Why This Part Fits

• RF Matching Networks: The 3.9nH ±0.3nH tolerance ensures accurate impedance matching in Bluetooth and Wi-Fi front-end modules, minimizing signal loss.
• DC‑DC Converter Output Filters: A 750mA current rating combined with 180 mOhm DCR reduces I²R losses, improving conversion efficiency in portable devices.
• High-Frequency Filtering: The SMD package and low parasitic capacitance make it suitable for suppressing EMI in 2.4GHz and 5GHz bands without degrading signal integrity.

Key Features & Advantages

• Ultra-Compact SMD Design: Occupies minimal PCB area, enabling dense layouts in wearables and IoT modules where board space is at a premium.
• Stable Inductance Over Frequency: The monolithic ceramic structure provides consistent 3.9nH inductance up to several GHz, ensuring predictable RF performance.
• Low DC Resistance (180 mOhm): Minimizes heat generation and voltage drop, allowing the inductor to handle 750mA with excellent thermal efficiency.
