Note:
1.
The frequency
f
c
is the frequency of minimum IL with the resonator
in the specified test fixture in a 50Ω test system with VSWR
≤
1.2:1.
Unless noted otherwise, case temperature TC = +25°C±2°C.
Frequency aging is the change in fC with time and is specified at
+65°C or less. Aging may exceed the specification for prolonged
temperatures above +65°C. Typically, aging is greatest the first year
after manufacture, decreasing in subsequent years.
Turnover temperature, T0, is the temperature of maximum (or
turnover) frequency, f0. The nominal frequency at any case
temperature, TC, may be calculated from: f =
f
o
[1 -

(T

].
This equivalent RLC model approximates resonator performance
near the resonant frequency and is provided for reference only. The
capacitance
C
O
is the measured static (nonmotional) capacitance
between input terminal and ground or output terminal and ground.
The measurement includes case parasitic capacitance.

The specifications of this device are based on the test circuit shown
above and subject to change or obsolescence without notice.
Typically, equipment utilizing this device requires emissions testing
and government approval, which is the responsibility of the
equipment manufacturer.
Our liability is only assumed for the Surface Acoustic Wave (SAW)
component(s) per se, not for applications, processes and circuits
implemented within components or assemblies.
