Typical Applications & Why This Part Fits

• RF Front-End Modules: The 4.7nH ±0.2nH tight tolerance ensures accurate impedance matching for GSM, Wi-Fi, and Bluetooth transceivers.
• High-Frequency Filtering: With a self-resonant frequency exceeding 6 GHz, this inductor suppresses unwanted noise in 2.4/5 GHz bands without degrading signal amplitude.
• DC-DC Converter Output Stages: The 700mA current capability and 160 mOhm DCR minimize power losses in buck/boost converters for portable electronics.

Key Features & Advantages

• 4.7nH Inductance at 100MHz: Provides predictable inductive reactance for resonant circuits and tuned filters.
• 700mA Rated Current: Supports moderate load currents typical of RF power amplifiers and processor supply lines.
• 160 mOhm DC Resistance: Reduces I²R heating and voltage drop, improving overall efficiency in power paths.
