ACT1018SMX-4
The ACT1018SMX-4 is an extremely compact, high quality, low aging, vacuum enclosed, seam
welded crystal. Utilising a ceramic base with a metal lid, it provides for the durability and reliability,
necessary for strenuous processes like infrared and vapour reflow. The lid is grounded through the
package, to assist with EMC Issues, and the pads are gold plated. The device is very suitable for
automatic placement on PCB's. With an excellent range of frequencies it is an optimum choice for
designs where PCB space is at a premium. Applications include: PDA, Cellular, MPU Clocks, ISM,
Bluetooth, WLan, and consummer electronics. Available loose or on reels (Standard 3,000 pieces /
reel.).

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 : A28MHz custom ACT1018SMX-4 device may have a part number such as CAV2800C- C1133-PF)
