Crystals Procurement Notes

Verify the exact frequency tolerance specification (±20ppm vs ±25ppm) against the official manufacturer datasheet prior to procurement, as conflicting data exists across sources. Confirm the package dimensions match the required PCB footprint. Ensure the supplier provides valid RoHS compliance documentation. Check current availability status as stock levels may vary significantly between distributors.

Crystals Selection Notes

Select this component when a standard HC-49/US footprint is required in a surface-mount configuration. The 12pF load capacitance suits common microcontroller and FPGA input requirements. Consider the ±20ppm or ±25ppm stability requirement relative to the application's timing sensitivity. Verify the operating temperature range meets the environmental conditions of the final product.

Crystals Part Context

This part belongs to the SXTHM2 series of crystals from Suntsu Electronics. It shares physical dimensions with other variants in the family but differs in frequency and tolerance.
