The future standard in generating a clocking signal !!

The X21 is a XY-cut SMD crystal that produces a specific frequency of 32.768 kHz.
We notice that this package size of 2.0 x 1.2 x 0.6 is becoming more popular for new designs that need a real-time clocking signal. As this evolution continues the price gap with today’s standard, the X31 (package: 3.2 x 1.5 x 0.9), will only get smaller.
This means that even more players on the global market will consider a change of package style due to this “smaller size for smaller price” evolution.
Features of the:  X21:

  • Frequency: 32.768 kHz
  • Package: 2.0 x 1.2 x 0.6 mm
  • Operating temperature range: -40°C to +85°C
  • Available with:
    • frequency tolerance at 25°C: 20ppm standard
    • Load capacitance: 12,5pF (standard), 9pF, 7pF or 6pF

The X21 is a 100 % equivalent for following tuning fork crystals that can be found on the market today:

  • ABS06
  • CM212
  • JTX210
  • FX122
  • CM8V
  • FC-12M
  • ST2012SB
