Fig. 2-1 shows the symbol for a ceramic resonator. The
impedance and phase characteristics measured between
the terminals are shown in Fig. 2-2. This illustrates that
the resonator becomes inductive in the frequency zone
between the frequency Fr (resonant frequency), which
provides the minimum impedance, and the frequency Fa
(anti-resonant frequency), which provides the maximum
impedance.
It becomes capacitive in other frequency zones. This
means that the mechanical vibration of a two-terminal
resonator can be replaced equivalently with a
combination of series and parallel resonant circuits
consisting of an inductor : L, a capacitor : C, and a
resistor : R. In the vicinity of the specific frequency
(Refer to Note 1 on page 8), the equivalent circuit can be
expressed as shown in Fig. 2-3.
Fr and Fa frequencies are determined by the
piezoelectric ceramic material and the physical
parameters. The equivalent circuit constants can be
determined from the following formulas. (Refer to Note
2 on page 8)
Fr=1/2π
Fa=1/2π
Considering the limited frequency range of Fr≦F≦Fa,
the impedance is given as Z=Re+j ω Le (Le≧0) as shown
in Fig. 2-4, and CERALOCK
inductance Le (H) having the loss Re (Ω).
