Observe precautions for handling! 1. 2. 3. 4. 5. 6. 7. 8. 9. The frequency fC is the frequency of minimum IL with the resonator in the specified test fixture in a 50 Ω test system with VSWR≤1.2:1. 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. Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f 0. The nominal frequency at 2 any case temperature, TC, may be calculated from: f = f 0 [1 - FTC (T 0 - TC) ]. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance C 0 is the measured static (non-motional) capacitance between input terminal and ground or output terminal and ground. The measurement includes case parasitic capacitance. Derived mathematically from one or more of the following directly measured parameters: f C, IL, 3 dB bandwidth, fC versus TC, and C0. The specifications of this device are based on the test circuit shown above and 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.
