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 two terminals.
