i.gif (807 Byte)Information (Quartz with ground lead)
The quartz units have a ground lead located in the middle between the normal leads.  Alternatively, the ground lead can be placed on the top of the case (ground top of case).
Quartz units with ground leads can be delivered in various specifications.  At the moment the delivery time is between 4 and 6 weeks.

Frequency Range
The technically available frequency range is from 3.276800 MHz to 70.000000 MHz.
At the moment it is not possible to manufacture quartz units in this case form outside of this range.

Extended Temperature Range

Quartz units with an extended temperature range (from -40°C to 85°C) are also available.   Other temperature ranges are also possible.  Please inquire.

Stability
We can deliver units with an exactness of 10 ppm.

Taping
All quartz units are also available with paper taping.
One reel in paper tape = 1000 pcs. Delivery time 6-8 weeks.
