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.

This equivalent RLC model approximates resonator performance near the

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:
