Notes:
1. The hermetic seal should be mounted as ush as possible with the hous-
ing. Excessive recession will create a high impedance air gap between
connection and housing which degrades electrical performance.
2. The use of an additional counterbore to accommodate a solder ring for
seal mounting is not recommended. A slight chamfer may be used if care
is taken to completely ll the area with solder - avoid air gaps .
