One or more of the following United States patents apply: 4,454,488; 4,616,197.
Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufac-
turer.
Unless noted otherwise, case temperature T

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: f
C
, IL, 3 dB bandwidth, f
C
versus T
C
, and C
O
.
Turnover temperature, T
O
, is the temperature of maximum (or turnover) frequency, f
O
. The nominal frequency at any case temperature, T
C
, may be
calculated from: f = f
O
[1 - FTC (T
O
- T
C
)

]. Typically,
oscillator
T
O
is 20擄 less than the specified
resonator
T
O
.
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 either pin 1 and ground or pin 2 and ground. The measurement includes case parasitic
capacitance.
