Information
The quartz units listed can be delivered immediately from our stock.   Frequently employed types are also stocked in larger amounts and available for immediate delivery.  Quartz units made to your specifications are also available through our company.

Frequency Range
The technically available frequency range is from 3.000000 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

Grounding
All quartzes can be delivered with a ground lead.  Delivery time is 4-6 weeks.  Soldering to the case, for example to attach a ground lead, should not be attempted, as this can destroy the quartz.  Instead, the H49SG should be used.

Accessories

For example, Insulators, see Accessories.
