For calculating the stability at 45 C? 1- Change in temperature (T) is (45-25) = +20 C 2 2- Change in frequency is (-0.035 x ( C) ) = 2 (-0.035 x (20) = -14 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- Quantities less than 3000 are shipped bulk in ESD pouches. 4- Specification subject to change without notice.
