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.
