Notes:
1. The center frequency, fC, is measured at the minimum IL point with
the resonator in the 50test system.
2. Unless noted otherwise, case temperature TC = +25°C ± 2°C.
3. Frequency aging is the change in fC 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.
4. Turnover temperature, T0, is the temperature of maximum (or
turnover) frequency, f0. The nominal frequency at any case
temperature, TC, may be calculated from: f = f0 [1 - FTC (T0 - TC)2].
5. This equivalent RLC model approximates resonator performance
near the resonant frequency and is provided for reference only. The
capacitance C0 is the measured static (nonmotional) capacitance
between Pin1 and Pin2. The measurement includes case parasitic
capacitance.
6. Derived mathematically from one or more of the following directly
measured parameters: fC, IL, 3 dB bandwidth, fC versus TC, and C0.
7. The specifications of this device are based on the test circuit shown
above and subject to change or obsolescence without notice.
8. Typically, equipment utilizing this device requires emissions testing
and government approval, which is the responsibility of the
equipment manufacturer.
9. 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.
