1- Standard Temperature Range does not need to be included in Part Number description.
2- Product is shipped in Tape and Reel conguration. Each reel contains 3000 pieces.
3- Specication subject to change without notice.
CTS3 Series
Frequency vs. Temperature Characteristics:
To calculate the frequency stability the parabolic
curvature constant (K) is needed.
For calculating the stability at 45 ° C?
1- Change in temperature (T) is (45-25) = +20 ° C
2- Change in frequency is (-0.034 x (° C)2) =
(-0.035 x (20)2 = -13.6 PPM
Option
