Connor-Winfield’s
precision SC crystals are
designed for high
frequency stability
ovenized applications. The SC crystals
are capable of achieving <5ppb/°C at
turning point.
The low profile coldweld package
allows for very low aging performance
in a reduced size.
Frequency Range: 20 to 100 Mhz
Frequency Calibration @ 85°C:
+/-1.0ppm
Aging: ppb / Day
Package: TO-5 Coldweld, 0.205” High
Designed for 0 to 70°C Ovenized
