Summary:

EMI suppresion capacitors and filters are common in automobile electronics today, but they are insufficient for heavy concentrations of wideband electromagnetic radiation. To resolve this problem, a highly-integrated Ceramic Absorber was developed to efficiently shield against frequencies from 1MHz to 1000MHz, which is mountable on the control circuit board easily, as it is the form of a flat plate strip line. This filter provides the signal line with an electromagnetic absorption effect through line transmission characteristics. Research into ceramic materials was required to determine the specific dielectric constants and frequency characteristics of ferroelectric ceramic materials.The development objective was material with optimum dielectric dispersion, as determined from research into energy absorption based on the Debye dielectric dispersion theory
