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. DIMENSIONS APPLICATIONS Military & Aerospace Satellite Space exploration systems Deep space probes Telemetry PACKAGING OPTIONS • Tray Pack (standard for Leaded, option for SM) • 16mm tape, 7” or 13” reels (only for SM) 1 Surface Mount FEATURES Radiation tolerance up to 100 kRad total dose High shock and vibration resistance Ultra high reliability Custom designs available Military and space screening available Low aging Designed, manufactured and tested in the USA Critical processes performed in class 10 cleanroom ded Lea unt Mo e c rfa Su TYPICAL Leaded TYPICAL DIM inches mm inches mm A 0.315 8.00 0.315 8.00 B 0.140 3.56 0.140 3.56 C (max) 0.070 1.78 0.070 1.78 D 0.045 1.14 0.310 7.87 E 0.060 1.52 0.020 1.02 F - - 0.150 3.81 03 Lead dimension Width = .018” (.46 mm) typical Thickness = .012” (.30 mm) typical 1.
