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.
