CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
NOTES:
1.
Aging may exceed the specification for prolonged temperatures above +65 °C.
Typically, aging is greatest the first year after manufacture, decreasing in subse-
quent years.
The center frequency, f
C
, is measured at the minimum insertion loss point, IL
MIN
,
with the resonator in the 50
Ω
test system (VSWR
≤
1.2:1). The shunt
inductance, L
TEST
, is tuned for parallel resonance with C
O
at f
C
. Typically,
f
OSCILLATOR
or f
TRANSMITTER
is approximately equal to the resonator f
C
.
One or more of the following United States patents apply: 4,454,488 and
4,616,197.
Typically, equipment utilizing this device requires emissions testing and
government approval, which is the responsibility of the equipment manufacturer.
Unless noted otherwise, case temperature T
C
= +25 ± 2 °C.
The design, manufacturing process, and specifications of this device are subject
to change without notice.
F
requency aging is the change in f
C
with time and is specified at +65 °C or less.

Derived mathematically from one or more of the following directly measured
parameters: f

Turnover temperature, T

, is the temperature of maximum (or turnover)
frequency, f

, may be
calculated from: f = f

This equivalent RLC model approximates resonator performance near the
resonant frequency and is provided for reference only. The capacitance C
O
is
the static (nonmotional) capacitance between the two terminals measured at low
frequency (10 MHz) with a capacitance meter. The measurement includes
parasitic capacitance with "NC” pads unconnected. Case parasitic capacitance
is approximately 0.05 pF. Transducer parallel capacitance can by calculated as:
C
P
≈
C
O
- 0.05 pF.

Electrical Connections
The SAW resonator is bidirectional and
may be installed with either orientation.
The two terminals are interchangeable
and unnumbered. The callout NC
indicates no internal connection. The NC
pads assist with mechanical positioning
and stability. External grounding of the NC
pads is recommended to help reduce
parasitic capacitance in the circuit.
