NOTES:  
1) Frequency aging is specified at 65°C or less.  
2) The center frequency Fc, is the frequency of minimum IL with the resonator in the  
specified test fixture in a 50Ω test system with VSWR <=1.2.  
3) Unless otherwise specified, case temperature is 25°C ± 2°C.  
4) The design model values are for reference only. The capacitance C0 is the  
measured static capacitance between either pin 1 and ground or pin 2 to ground.
