Surface Mount Watch Crystal
XT32P
Vishay Dale
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.
FEATURES
Low profile
Industry standard footprint
Long term stability
Tape and reel, 2000 pcs
100 % Lead (Pb)-free and RoHS compliant
DIMENSIONS in inches [millimeters]
PARABOLIC TEMPERATURE CURVE
To determine frequency stability, use parabolic curvature (k).
For example: What is stability at 45 °C?
1) Change in Temperature (°C) = 45 - 25 = 20 °C
2) Change in Frequency = - 0.042 ppm*(
Δ°C)
= - 0.042 ppm*(20)2
= - 16.8 ppm(max)
