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.
The center frequency, fC, is measured at the minimum insertion loss point, ILMIN,
with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The shunt
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically,
fOSCILLATOR or fTRANSMITTER is approximately equal to the resonator fC.
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 TC = +25 ± 2 °C.
The design, manufacturing process, and specifications of this device are subject
to change without notice.

Derived mathematically from one or more of the following directly measured
parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
Turnover temperature, TO, is the temperature of maximum (or turnover)
frequency, fO. The nominal frequency at any case temperature, TC, may be
calculated from: f = fO [1 - FTC (TO -TC)2]. Typically oscillator TO is
approximately equal to the specified resonator TO.
This equivalent RLC model approximates resonator performance near the
resonant frequency and is provided for reference only. The capacitance CO 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:
CP ≈ CO - 0.05 pF.
Tape and Reel Standard Per ANSI / EIA 481.

Pin
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.
