SWCX1 SWEPT QUARTZ CRYSTALS
6 MHz to 250 MHz
Radiation Resistant, Miniature Surface Mount
and Leaded Quartz Crystals
DESCRIPTION
For applications that require resistance to radiation, Statek
offers our swept quartz AT-cut resonators. Made with cultured
quartz that is electrically "swept" at high temperature to
remove interstitial impurities within the crystalline structure,
these resonators are superior to those utilizing non-swept
quartz in maintaining their frequency and other electrical
characteristics under exposure to radiation levels of 100 krad
(1 kGy) and greater. As Rad-Hard applications typically
require various degrees of high-reliability components,
Statek offers these resonators in three distinct screening
options to meet mission critical program requirements from
Engineering to Flight.
