Ceramic resonators are cheaper than
crystals
Now available in a surface-mount ceramic design, a new space saving range of ceramic resonators from Advanced Crystal Technology offers a low-cost alternative to surface-mount crystals.

Crystals shrink to the surface
Advanced Crystal Technology has further reduced the size of surface-mount crystals by introducing the ACT200.
These new ceramic resonators comprise four product families; the ACT ZTAC and ACT ZZMB, two-pad devices and the ACT ZTTC and ACT ZTMD, three-pad devices, the latter having built in capacitors.
Each family covers a frequency range from 1.79 to 50.00MHz and operates across a temperature range of -20 to +80C.
Measuring from just 7.4 x 3.4 x 1.8 to 3.7 x 3.1 x 1.2mm, these resonators are suitable for pick and place with other surface mount components, cutting out the need for hand soldering.
The ACT ZTAC and ACT ZTTC have a frequency tolerance of +/-0.5%, at 25C, while the ACT ZTMD and ACT ZZMB has a tighter frequency tolerance of +/-0.3% at 25C.
The standard temperature stability for the majority of the family is +/-0.3%.
All types have low aging characteristics over 10 years of +/-0.3%.
