Crystals Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact electrical tolerances and aging rates. Ensure the selected variant matches the required load capacitance and ESR limits for the target oscillator circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a hermetically sealed SMD crystal is required for frequencies near 18.432 MHz. Evaluate the 40 Ohm ESR limit against the oscillator amplifier's drive capability. Confirm that the 18 pF load capacitance aligns with the circuit's stray capacitance requirements to maintain frequency accuracy.

Crystals Part Context

This part belongs to the 407 Series of surface-mount crystals from CTS-Frequency Controls. The series utilizes AT-cut quartz elements housed in hermetic ceramic packages, offering superior stability compared to standard epoxy-sealed alternatives. It serves as a passive frequency-determining element in electronic circuits.
