The shunt inductance, Ltest, is tuned for parallel resonance with Co at fc. Typically, fOSCILLATOR or fTRANSMITTER is approximately equal to the resonator fc. 3) Turnover temperature, To, is the temperature of maximum (or turnover) frequency, fo. The nominal frequency at any case temperature, Tc, may be calculated from: f = fo(1-FTC(To-Tc)2). Typically oscillator To is 20℃ less than the specified resonator To. 4) 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. 5) This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance Co is the static (nonmotional) capacitance between pin1 and pin2 measured at low frequency (10MHZ) with a capacitance meter. The measurement includes case parasitic capacitance with a floating case. For usual grounded case applications (with ground connected to either pin 1 or pin 2and to the case), add approximately 0.25pF to Co. 6) Derived mathematically from one or more of the following directly measured parameters: fc, IL, 3dB bandwidth, fc versus T 3. Others 1) Typically, equipment utilizing this device requires emissions testing and government approval, which 2) 3) is the responsibility of the equipment manufacturer. Electrostatic Sensitive Device, observe precautions for handing.
