Chip module for surface mounted device - with ceramic or ferrite plate for conductive turns representing LC oscillator circuit

摘要

Chip module for use as a surface mounted device (SMD) is a cubical insulator body of ceramic or ferrite plates with grooves filled with conductive material to form coils of defined inductance. The chip represents an LC-oscillator circuit, the inductance being determined by the geometry of the coil turns, and the capacitance by the dielectric constant, loss angle and insulation resistance of the ceramic plates. ADVANTAGE - This produces chip modules for use as oscillator circuits, bandpass filters or miniature transformers without need for an SMD casing.
