Product Overview
This series of high-frequency chip ceramic wire-wound inductors offers high Q values and high self-resonant frequencies due to its ceramic material. Designed for surface mounting, these inductors feature small chip sizes, tight inductance tolerances, and high reliability. They are ideal for applications in mobile phones (TD-LTE/5G communication), high-frequency circuits in communication equipment, Bluetooth, W-LAN, and broadband networks.
