1. The frequency f_C is the frequency of minimum IL with the resonator in the specified test fixture in a 50Ω test
system with VSWR ≤ 1.2:1. Typically, f_OSCILLATOR or f_TRANSMITTER is less than the resonator f_C.
2. Unless noted otherwise, case temperature T_C = +25°C±2°C.
3. 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.
4. Turnover temperature, T₀, is the temperature of maximum (or turnover) frequency, f₀. The nominal frequency at
any case temperature, T_C, may be calculated from: f = f₀ [1 - FTC (T₀ - T_C)²]. Typically, oscillator T₀ is 20° less
than the specified resonator T₀.
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 either Pin 1 and
ground or Pin 2 and ground. The measurement includes case parasitic capacitance.
6. Derived mathematically from one or more of the following directly measured parameters: f_C, IL, 3 dB bandwidth, f_C
versus T_C, 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.
