Crystals Procurement Notes

Verify the specific ordering suffix to confirm the exact load capacitance value, as variations exist within the 402F27133 series. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements specified in the manufacturer datasheet. Confirm availability status directly with authorized distributors, as supply chain conditions may affect immediate procurement.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with a 9pF load capacitance. Consider the ±30ppm stability limit against the system's jitter budget. Evaluate the 100 Ohm ESR against the oscillator circuit drive level constraints. Compare package dimensions against available board space and thermal management requirements.

Crystals Part Context

This part belongs to the CTS 402 Series of quartz crystals, which covers frequencies from 1.8432 MHz to 64 MHz. The series offers both fundamental and third overtone modes.
