ACT631SMX-4
The
ACT631SMX-4
is a 4 pad, high quality, low aging, metal seam, packaged crystal suitable for automatic
placement on printed circuit boards. It utilises a ceramic base and metal lid for durability. the lid is grounded
through the package and the pads are gold plated. With a wide frequency range, and tight stability it has
become one of the optimum choices for design engineers.
Applications
include Communications,
Microprocessor Systems, Instrumentation and many more.

NOTES :
1)
Tighter Tolerances and Stabilities and other Operating Temperature Ranges may be available.
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 ACT631SMX-4 device may have a part number such as PA1200C- C1122-PF)
3)
A guide to availability of tighter stabilities appears on page one of this data sheet and above in Table 2
4)
Frequencies below 10.000MHz are prefixed with a "0" (eg: 0900 = 9MHz.Whereas 10.000MHz is 1000 )
