World's smallest crystal measures 1 x 0.8 MM for smart phones and wearables

Date: 12/04/2017
Japanese passive component maker Kyocera is offering an alternate crystal oscillator as a replacement for its CX1210 model, where the new one meets most of the the electrical specifications but is smaller in size making it suitable for smart phones and wearable electronics. It is hard to cut the size of crystal oscillator without compromising its performance but Kyocera could do this by optimising the design using its own piezo-electric analysis technology
Kyocera has used ultra-high-precision processing (plasma CVM technology) developed with Yamamura. Kyocera has also used its proprietary semiconductor processing technology for accurate external dimensions, and minimal variation in equivalent series resistance, for optimal performance at reduced size.

The new crystal oscillator CX1008 measures 1.0 x 0.8mm and can replace CX1210 without any electrical circuit revision.

The samples the new crystal oscillators are expected to be available in May 2007 and mass production scheduled for early 2018.
