Crystals Procurement Notes

Verify the specific manufacturer source, as catalog data indicates potential discrepancies regarding the original equipment manufacturer designation between FTS and TXC Corporation. Confirm the exact frequency stability specification of ±50ppm against the official datasheet, as some listings reference different stability values for similar part numbers. Ensure the RoHS compliance status is documented in the current production release documentation before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 18.432 MHz fundamental frequency crystal is required for surface mount applications. The 40 Ohm ESR value should be matched against the oscillator circuit requirements to ensure proper startup and stable operation. Consider the ±50ppm stability rating for applications where moderate frequency accuracy is sufficient. Verify that the 5.0x3.1 mm footprint fits within the available PCB area constraints.
