Electrical Connections
The SAW resonator is bidirectional and
may be installed with either orientation.
The two terminals are interchangeable
and unnumbered. The callout NC indi-
cates 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.
