With the trend toward miniaturization and integrated functions of sets, reduction in mounting space and thickness of the components to be incorporated in equipment is more strongly required.
Through improvement of the processing methods and development of new piezoelectric materials, Murata has promoted miniaturization of ceramic resonators ("CERALOCK®"), and now offers designs as small as 2.5 x 2.0mm (3.2 x 1.3mm) and as thin as 0.65mm (1.0mm) earlier than other manufacturers.
You can expect further reduction in size and thickness in the future.

With the trend toward an increased number of electric equipment for automobiles, system modularization and miniaturization of the car body while ensuring sufficient space, the possibility that sets incorporating the "CERALOCK®" will be used in an engine compartment will be increasing in the future.
As the temperature requirements for the components are raised (85°C 
125°C 150°C), improved thermal shock resistance is also required for the components.
Murata has been improving piezoelectric materials for automotive equipment, and now guarantees their operation at high temperatures (up to 125°C) as its standard. Furthermore, Murata has strived to develop highly heat-resistant piezoelectric materials in order to ensure operation at even higher temperatures (up to 150°C).
