The centre frequency, f C, is measured at the minimum IL point with the resonator in the 50 Ω test system.
Unless noted otherwise, case temperature T C = +25°C±2°C.
Frequency aging is the change in f C with time and is specified at +65°C or less. Aging may exceed the
specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after
manufacture, decreasing in subsequent years.
Derived mathematically from one or more of the following directly measured parameters: f C, IL, 3 dB
bandwidth, fC versus TC, and C 0.
The specifications of this device are 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.
In keeping with our ongoing policy of product evolvement and improvement, the above specification is subject to change without notice.
