Frequency aging is the change in f
specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after manufacture,
decreasing in subsequent years.

The specifications of this device are based on the test circuit shown above and subject to change or
obsolescence without notice.
Typically, equipment utilizing this device requires emissions testing and government approval, which is the
responsibility of the equipment manufacturer.
Our liability is only assumed for the Surface Acoustic Wave (SAW) component(s) per se, not for applications,
processes and circuits implemented within components or assemblies.
