Crystals Procurement Notes

Verify the specific package variant against the HC49S designation when sourcing. Confirm that the 20 pF load capacitance matches the target circuit design requirements. Ensure the ±30 ppm tolerance meets the system's frequency stability needs. Check RoHS compliance status as indicated in official documentation before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required for surface mount designs. The 40 Ohm ESR value should be compatible with the oscillator circuit's drive level constraints. Consider the -40°C to +85°C range for industrial or outdoor environments. Verify pin compatibility if replacing existing through-hole designs with surface mount equivalents.

Crystals Part Context
