Product features
32.768KHz is easier to frequency division so as to generate a 1
second clock frequency, because 32768 is equal to 2 of the 15
square. We use watches every day, mobile phones, computer shows the
role of the clock is evolved from it
Standard Environmental Condition:
Environmental Temperature:15℃~35℃
Humidity:45%~85%
Atmospheric pressure:86~106KPa
Operating Temperature Range:-20℃~70℃
Crystal Frequency & Resistance will be tested under the following
conditions,
Unless extra requirments:
standard temperature(25±2℃) after heat balance.
Storage Temperature Range:-40℃~+85℃
Mechanical test:
The quartz crystal unit shall be subjected to normal atmospheric
conditions for 1hr before being tested.
Dropping Test:
The Units are measured for its frequency and resistance in
accordance with Table1 & without mechanical damage,after allowing
the crystal to fall freely.
From 75 cm of height 3 times on the firmed wood.
Vibration Test:
The Units are measured for its frequency and resistance in
accordance with Table 1&without mechanical damage afer
subjectiong to 2hrs of vibration with 0.75mm amplitude with 10~55Hz
frequency sweep 20 times.
Sealing Tightness:
Find Lead Test:≤1×10-8atm·cc/S by Helium mass-mass-spectrometer detector,and vacuum and
reach 1×10-3Pa；
Resistance to Soldering Heat:
The Units are measured for its frequency and resistance in
accordance with Table 1 after dipping into molten solder with the
temperature of 320℃±10℃；For 3~4 secs and at a depth up to a point
2.0mm from the base root.
