The presentations covered ceramic multi-layer devices, surface acoustic wave filters, and dielectric filters. Murata ceramics are known as the best in the world. Dielectric constants range from 20 to 13,000. A value of 3000 is most popular. In addition ferrite materials are used to develop transformers and noise suppression filters.
Pyroelectricity is material property explored by the company for sensor development.
Furthermore semiconductor materials are used for the development of thermistors. The kind of device used for filtering depends, among others, on frequency and power levels. Thus SAW filters are good at lower power levels and better at the lower frequencies. Ferrites are glossy ceramics attenuating because of their magnetic properties and are used for EMI suppression. As with presentations at all sites, not all the work in Kyoto could be covered.
