Electrical Connections
Equivalent Model
The SAW resonator is bidirectional and may be
installed with either orientation. The two terminals
Terminal
0.05 pF*
are interchangeable and unnumbered. The callout
NC indicates no internal connection. The NC pads
assist with mechanical positioning and stability.
Cp
Co = Cp + 0.05 pF
*Case Parasitics
External grounding of the NC pads is
recommended to help reduce parasitic

capacitance in the circuit.
Temperature Characteristics
Typical Test Circuit
The test circuit inductor, L TEST , is tuned to resonate with the static
capacitance, C O , at F C .
The curve shown on the right
accounts for resonator
contribution only and does not
include LC component
temperature contributions.
