NOTES :
1)
Tighter Tolerances and Stabilities and other Operating Temperature Ranges may be available.
As each of these specification parameters impact on each other, it is not always possible to combine all options in one
device. Therefore, if a specification not catered for above is required, please contact us directly for the relevant part
number code(s).
2)
ACT are always happy to consider truly custom specification parts which may require non-standard specification
parameters, specific testing, customer requested AQL requirements, non standard packaging or taping and reeling and
custom marking. Such devices would normally be allocated a custom specification part number which is wholly customer
specific.
(
EG : A 12.00MHz custom ACT325MX-4 device may have a part number such as BT1200C- C1122-PF)
3)
A guide to availability of tighter stabilities appears in Table 2 of the data sheet
4)
Frequencies below 10.000MHz are prefixed with a "0" (eg: 0900 = 9MHz.Whereas 10.000MHz is 1000 ) See main data sheet
for available frequency range.
