CRYSTALS CRYSTALS
The ECS-31 Series features the same
characteristics as only tuning fork crystals
offer. Because of their miniature size they are
ideal for portable and communication
equipment applications.
FEATURES
Miniature size
Cost effective
Long term stability
Excellent shock and vibration characteristics

T (C)
To determine frequency stability, use parabolic
curvature. For example: What is the stability at 45C
1) Change in T (C) = 45 -25 = 20C
2) Change in frequency = -0.04 PPM x (
T)

= -0.04 PPM x (20)
= -16.0 PPM
