1] 6I Stability/Temperature combination is not available.
2] These stabilities are not recommended for new designs.
3] Frequency is recorded with only leading significant digits before the ‘M’ and 4 - 6 significant digits after the ‘M’ (including zeros).
[Ex. 3.579545 MHz, code as 3M579545; 14.31818 MHz, code as 14M31818; 125 MHz, code as 125M0000]
4] CTS Distributors may add a -T or -1 at the end of the part number to indicate Tape and Reel packaging.
Not all performance combinations and frequencies may be available.
Contact your local CTS Representative or CTS Customer Service for availability.
