Kyocera's new generation of ultra-small crystal units (CX1008SB series) components - WINNER of the Japan Ministry of Education, Culture, Sports, Science and Technology (MEXT) award for technology development in 2021 for achieving the same performance as our previous crystal units with a 33% reduction in size.
Normally, downsizing from 1.2 x 1.0mm to 1.0 x 0.8mm components would increase equivalent series resistance and require circuit board revision. However, by optimizing the design using piezoelectric analysis technology, Kyocera has downsized this device to 1.0 x 0.8mm with the same electrical characteristics as our conventional technologies. This allows engineers to incorporate the new CX1008SB series components without revising circuit designs.
