This group includes passive electronic components designed for energy storage, filtering, and signal conditioning in a wide range of electronic applications. Inductors: Store energy in a magnetic field when current flows through them, used in power supplies, filters, and oscillators. Coils: Wound wire components that serve as inductors or transformers, commonly used in RF and high-frequency applications. Chokes: Specialized inductors designed to block or filter high-frequency signals while allowing DC or low-frequency signals to pass, ideal for power line noise suppression. These components are crucial for managing electrical signals, minimizing interference, and optimizing performance in power management, signal processing, and communication systems.
