X: Traceability code)
TEST CIRCUIT:
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 3 to ground.
