A chip inductor, also known as a surface-mount inductor or SMD (Surface-Mount Device) inductor, is an electronic component used in a wide range of electronic circuits. It is designed to provide inductance, which is a property of passive electronic components that allows them to store energy in the form of a magnetic field when current flows through them.
1. Inductance: The primary function of a chip inductor is to provide a specific value of inductance, typically measured in henrys (H), millihenrys (mH), or microhenrys (µH). This inductance value determines how effectively the component stores energy in its magnetic field.
2. Construction: Chip inductors consist of a coil of wire wound around a core material. The core material can vary and may include ceramic, ferrite, or other magnetic materials. The wire used in the coil can be made of copper or other conductive alloys.
