PTX series

The PTX series is designed as surface mount crystals.

Some important specifications of PTX series have been concluded into several points as follow. The first one is about its frequency range which would be from 3.579MHz to 72.000MHz. The next one is about is tolerance at 25°C which would be ±10ppm for D and ±15ppm for F and ±20ppm for G and ±30ppm for J and ±50ppm for M and ±100ppm for P. The next one is about its stability which would be ±15ppm for F and ±20ppm for G and would be ±25ppm for H and would be ±30ppm for J and ±50ppm for M and would be ±100ppm for P. The next one is about its aging which would be ±5ppm / yr.max. The next one is about its standard operating conditions which would be from 0°C to +70°C for 1 and would be from -40°C to +85°C for 2 and would be from -10°C to +60°C for 3 and would be -20°C to +70°C for 6. The next one is about its storage temperature range which would be from -55°C to +105°C. The next one is about its shunt capacitance which would be max 7 pF. The next one is about its load capacitance which would be 18pF std.

And some other specifications about PTX series. The first one si about its equivalent series resistance (ESR), max, fundamental (AT cut) which would be 180 from 3.579MHz to 3.999MHz and it would be 150 from 4.000MHz to 4.999MHz and it would be 100 from 5.000MHz to 6.999MHz and it would be 50 from 7.000MHz to 14.999MHz and it would be 40 from 15.000MHz to 23.999MHz and it would be 30 from 24.000MHz to 40MHz and for third overtone (AT cut) which would be 80 from 40.000MHz to 72.000MHz. The next one is about its drive level which would be 100uW max. The next one is about its hold which would be HC-49/US-SMD. The next one is about its mechanical shock which would be MIL-STD-202, mothod 213,C. The next one is about its vibration which would be MIL-STD-202, method 201 & 204. And so on.
