Crystals Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration as documented in official TXC materials. Confirm that the AEC-Q200 qualification status applies to this exact part number variant. Ensure compatibility with the HC-49S footprint dimensions during PCB layout verification. Cross-reference the datasheet revision date to confirm current electrical specifications against design requirements.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required for digital signal processing or communication interfaces. The HC-49S SMD form factor suits applications needing robust mechanical stability in compact enclosures. Consider the ±30 ppm stability limit for systems tolerant to moderate environmental temperature variations between -20°C and +70°C.
