Epson Toyocom Corp. has released an ultrathin SMD tuning fork crystal unit. The FC-13F measures 3.2-by-1.5-by-0.6mm, making it a good fit for mobile devices.

The company said it was able to achieve the small size by using a combination of quartz microelectromechanical systems (QMEMS) and high-precision technologies. The FC-13F provides almost the same performance as the previous 32.768kHz FC-135 model. Except for thickness, the FC-13F has the same external dimensions as the FC-135 currently in production.

The FC-13F features a standard frequency tolerance of—20 x 10-6 (25°C) and a motional resistance of 80 kiloohms maximum. The turnover temperature is 25°C ±5°C.

The product is currently available in volume production.
