For calculating the stability at 45 ° C? 1- Change in temperature (T) is (45-25) = +20 ° C 2 2- Change in frequency is (-0.034 x (° C) ) = 2 (-0.035 x (20) = -13.6 PPM Notes: 1- Standard Temperature Range does not need to be included in Part Number description. 2- Product is shipped in Tape and Reel configuration. Each reel contains 3000 pieces. 3- Specification subject to change without notice. Page: 4/4 Date: Oct. 21, 2018 P/N: www.aker-usa.com CTS3 Series
