PACKAGE HANDLING
The CX crystal is hermetically sealed in a ceramic package. Normal
handling and soldering precautions for small, low thermal mass parts
are adequate when installing or testing CX crystals. CX crystals may
be wave soldered with proper precaution taken to avoid desoldering
the leads. A slow machine rate or too high a pre-heat temperature or
solder bath temperature may damage the crystals. Lead to package
solder interface temperature should not exceed 175°C, glass lid
to package seal rim temperature should not exceed 210°C. If
the seal rim reaches temperatures above the maximum specified, the
package may lose its hermeticity. Loss of hermeticity results in a
frequency decrease and motional resistance increase.
STANDARD FREQUENCIES
10.0, 11.0592, 12.0, 16.0, 19.66080, 20.0, 24.0,
24.576, 30.0, 32.0, 35.2512, 36.0 and 40.0MHz
