QETF26-GW

The QETF26-GW is designed with tuning fork 32.768KHz with clock for communication equipment.

Some electrical characteristics of QETF26-GW have been concluded into several points as follow. The first one is about its frequency range which would be typ 32.768KHz. The next one is about its operating temperature range which would be from -20°C to 70°C. The next one is about its storage temperature range which would be from -40°C to 85°C. The next one is about its frequency tolerance (at 25°C) which would be max ±20 ppm refer at 25°C. The next one is about its frequency stability which would be -0.04 x ( °C)2 with condition of turn over temp. at 25°C ± 5°C. The next one is about its aging (first year) which would be max ±5 ppm ref at 25°C. The next one is about its load capacitance which would be typ 12.5 ± 0.2pF. The next one is about its shunt capacitance which would be max 2pF. The next one is about its series resistance which would be max 50K. The next one is about its drive level which would be min 0.8W and typ 1.0W and would be max 1.2W. The next one is about its insulation resitance which would be min 500M at 100Vdc. That are all the main characteristics.

Also environmental specifications of QETF26-GW have been concluded into several points as follow. The first one is about its vibration test which would be subject sample to 2-mimute cycles (frequencies from 10 to 500Hz) with 1.5mm amplitude or 100g acceleration during 2 hrs in each direction (X,Y,Z). 6 hours in total. The next one is about its shock test which would be Orient the sample in any attitude and drop it 3 times from a height of 50cm onto a hardwood board with a thickness of 3cm. And so on.
