ACT ZTACS SMD Resonators
The
ACT ZTACS
family comprise of a range of surface mount, ceramic
resonators ("chip" type) in two pad format. This family offers a cost effective
solution to those applications where a wide temperature range, accuracy to ± 0.5,
small size and surface mounting are the requirements.

For frequencies from 5.0 to 8.0MHz it is recommended to use ZTACC MG series as the characteristics are better.
Most frequencies of the ZTA CS will eventually be phased out in favour of the smaller package devices. For new
applications the ZTACV MT is recommended for frequencies from 8 to 13MHz and the ZTACV MX for 16 to 60MHz.

Important note when using Ceramic resonators with micro controllers:
Some resonator parameters vary considerably with frequency and physical construction/size . These differences are too
great to be able to be practically shown in a data sheet.
However, these parameters can be critical when the resonators are used with micro controllers. Even if two different
resonators appear to have the same specification the typical values of these critical parameters can be considerably
different. When enquiring about resonators for use with micro controllers it is important to supply the make and part
number of the IC to be used and/or the list of recommended resonators, if this is given.
Please note that all parameters can not necessarily be specified in the same device
