Tape and reel, 2000pcs
The XT32P is a cylinder type watch crystal molded in a
thermoplastic housing capable of withstanding soldering
re-flow processing. The XT32P is perfect for your SMD
applications using the 32.768 KHz frequency. We offer two
different footprints of the part to satisfy various pattern layout
requirements.

To determine frequency stability, use parabolic curvature (k).
For example: What is stability at 45 擄C?
1) Change in Temperature (擄C) = 45 - 25 = 20 擄C
2) Change in Frequency = - 0.042 ppm*(鈭喡癈)
= - 0.042 ppm*(20)
2
= - 16.8 ppm(max)
