QESM042

The QESM042 is designed as SMD 6.0x3.5 crystal with ceramic SMD 2 pads packaged.

Some electrical characteristics of QESM042 have been concluded into several points as follow. The first one is about its frequency range which would be min 10MHz and max 80MHz. The second one is about its frequency tolerance (at 25°C) which would be min ±10 ppm and typ ±30 ppm and max ±50 ppm refer to ordering information. The third one is about its temperature stability which would be min ±10 ppm and typ ±30 ppm and max ±50 ppm refer to ordering information. The fourth one is about its operating temperature range which would be typical -20°C/+70°C and would be max -40°C/+85°C refer to ordering information. The fifth one is about its storage temperature range which would be from -40°C to +85°C. The sixth one is about its shunt capacitance which would be max 7.0pF. The seventh one is about its load capacitance which would be from 10pF to 30pF or series refer to ordering information. The eighth one is about its drive level which would be typ 10W and would be max 100W. The ninth one is about its aging (first year) which would be max ±3 ppm ref at 25°C. The tenth one is about its insulator resistance which would be min 500M at 100Vdc. That are all the main characteristics.

Also mechanical conditions have been concluded into several points as follow. The first one is about its vibration which would be 10g, 10Hz to 2KHz according to standard CEI 68-2-63. The second one is about its shocks which would be 100g, 6ms according to standard CEI 68-2-27.

And marking for QESM042 that the line 1 would be manuf code +temex code (6 digits) and line 2 would be frequency in MHz (6digits). And so on. If you have any question or suggestion or want to know more information please contact us.
