Part Numbering Guide
Description
The HFX7 Series is a very high fre-
quency miniature AT-cut resonator
housed in a standard 5x7 mm ceramic
package. The parts exhibit excellent ag-
ing and stability characteristics. Tab-
Mesa Technology TmT
TM
, proprietary
to Saronix, is used to achieve funda-
mental resonators to 250 MHz.
