ECS-31 SERIES LOW FREQUENCY QUARTZ 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

f/f (PPM)
To determine frequency stability, use parabolic
curvature. For example: What is the stability at 45˚C?
1) Change in T (˚C) = 45 -25 = 20˚C
2) Change in frequency = -0.04 PPM x (∆T)2
= -0.04 PPM x (20)2
= -16.0 PPM
