com Notes: 1.
The center frequency, fC, is measured at the minimum IL point with the resonator in the 50Ω test system.
Unless noted otherwise, case temperature TC = +25°C ± 2°C.
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.
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].
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.
