XT38P
Vishay Dale
Miniature SMD Watch Crystal
FEATURES
2.5 mm height
Industry standard footprint
Long term stability
Tape and reel, 3000 pcs
100 % Lead (Pb)-free and RoHS compliant
The XT38P is a 2.5 mm height plastic molded 32.768 KHz
SMD crystal unit. This thermoplastic molded rugged part is
perfect for your SMD applications in limited circuit space
using the watch frequency.
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*(
°C)
= - 0.042 ppm*(20)
2
= - 16.8 ppm(max)
