ECX-71

      The miniature ECX-71 is designed as a very compact SMD tuning fork crystal. The 7 x 1.5 x 1.4 mm plastic package is ideal for today's SMD manufacturing environment.
      ECX-71It has four features. The first one is that it would have low profile. The second one is that it would have 7 x 1.5 mm footprint. The third one is that it would have extended temperature range. The next one is that it would be RoHS compliant. That are all the features.
      Some operating conditions and electrical characteristics of ECX-71 have been concluded into several points as follow.The first one is about its frequency which would be typ 32.768KHz.The second one is about its frequency tolerance which would be max +/- 20 ppm. The next one is about its load capacitance which would be typ 12.5 pF.The next one is about its drive level which would be typ 0.1uW and max 1.0uW.The next one is about its equivalent series resistance which would be max 65k.The next one is about its turnover temperature which would be min +20°C and typ +25°C and max +30°C.The next one is about its temperature coefficient which would be min -0.025 ppm/°C2 and would be typ -0.035 ppm/°C2 and would be max -0.045 ppm/°C2. The next one is about its shunt capacitance which would be typ 0.8 pF. The next one is about its first year aging which would be max +/- 3ppm with condition of the temperature to be +25°C ±3°C. The next one is about its operating temperature which would the minimum of -40°C and would have the maximum of +85°C. The next one is about its storage temperature which would have the minimum of -55°C and would be maximum of +125°C. The next one is about its reflow frofile which would be max +260°C. And so on.
