Citizen's CFS145 series features a 1.4 x 5.0 mm cylinder type through-hole package. Load capacitance is 12.5 pF. The frequency tolerance for these devices is ±20 ppm at 25°C with an operating temperature range of -20°C ~ +70°C.
The CFS206 series features a 2.0 x 6.0 mm cylinder type through-hole package. There are load capacitance choices of 6.0 and 12.5 pF. There are frequency tolerances choices of ±5, ±10, and ±20 ppm at 25°C with an operating temperature range of -20°C ~ +70°C.
Both the CFS145 and CFS206 series crystals are excellent choices as the clock source for portable devices requiring low power consumption.
