Connor-Winfield’s
precision SC crystals
are designed for high
frequency stability
ovenized applications.
The SC crystals are
Frequency Range: 8.192 to 32 MHz
Frequency Calibration @ 85°C:
+/-1.0ppm
Aging: ppb / Day
Package: TO-8, 0.200” High
Designed for 0 to 70°C Ovenized
Applications
capable of achieving <5ppb/°C at
turning point. The low profile coldweld
package allows for very low aging
performance in a reduced size.
