Thin kHz-band Crystal Unit from Texim
Epson Toyocom has succeeded in commercially developing an extremely thin kHz-band crystal unit. The new tuning-fork crystal unit, called the FC-13E, has a maximum thickness of just 0.48 mm.
The The market for high-function secure smart cards, has been expanding in recent years. This expansion has driven strong demand for thinner cards, most notably credit cards, equipped with a time management function, the key component of which is a kHz-band crystal unit. The challenge for crystal device manufacturers was to develop an SMD-type kHz-band crystal unit with a thickness of less than 0.5 mm.
Epson Toyocom is answering these demands with the FC-13E. The material thickness of the package has been optimized, and the package is hermetically sealed with a gold-tin alloy. The FC-13E is approximately 20% thinner than its predecessor, the FC-13F. By trimming the maximum thickness down to 0.48 mm from 0.6 mm, Epson Toyocom is enabling the realization of secure, thin smart cards equipped with a time management function. Frequency tolerance, an indicator of accuracy, is ± 100 x 10-6. The FC-13E is EU RoHS compliant. More information on this new product can be obtained from Texim Europe.
