Observe precautions for handling! NOTES: 1. Frequency aging is the change in fC with time and is specified at +65℃or less. Aging may exceed the specification for prolonged temperatures above +65℃. Typically, aging is greatest the first year after manufacture, decreasing in subsequent years. 2. The center 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. Typically, foscillator or ftransmitter is less than the resonator fC. 3. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer. 4. Unless noted otherwise , case temperature TC=+25℃±2℃. 5. The design, manufacturing process, and specifications of this device are subject to change without notice. 6 .Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fC versus TC , and CO. 7. Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO, The nominal center frequency at any case temperature , TC, may be calculated from :f = fO[1-FTC (TO-TC) ].Typically, oscillator TO is 20℃ less than the specified resonator TO. 8. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only . The capacitance CO is the measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground .The measurement includes case parasitic capacitance with a floating case. For usual grounded case applications (with ground connected to either pin 1 or pin 2 and to the case), add approximately 0.25 pF to CO. 2 Free Datasheet http://www.datasheet4u.com/ .
