1. The center frequency, fC, is measured at the minimum IL point with
the resonator in the 50Ω test 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].
ww5w. .DaTthaisSehqeueivt4aUlen.ct oRmLC 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
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.
