Notes:
1.
The center frequency,
f
C
, is measured at the minimum IL point with
the resonator in the 50鈩?test system.
Unless noted otherwise, case temperature
T
C
= +25擄C 鹵 2擄C.
Frequency aging is the change in
f
C
with time and is specified at
+65擄C or less. Aging may exceed the specification for prolonged
temperatures above +65擄C. Typically, aging is greatest the first year
after manufacture, decreasing in subsequent years.
Turnover temperature,
T
0
, is the temperature of maximum (or
turnover) frequency,
f
0
. The nominal frequency at any case
temperature, T
C
, may be calculated from:
f
=
f

(T

].
This equivalent RLC model approximates resonator performance
near the resonant frequency and is provided for reference only. The
capacitance
C
0
is the measured static (nonmotional) capacitance
between Pin1 and Pin2. The measurement includes case parasitic
capacitance.
