Crystals Procurement Notes

Verify the manufacturer designation carefully, as sources list both FTS and TXC Corporation for this part number. Confirm RoHS compliance status and lead-free specifications directly with the supplier or original datasheet to ensure alignment with project requirements. Cross-reference the exact package dimensions and electrical parameters against the official documentation before procurement.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency crystal is required with ±30 ppm total stability. Ensure the circuit design supports a 12 pF load capacitance and can drive the 50 Ohm ESR specification. Verify that the 2-SMD footprint matches the board layout constraints and that the operating temperature range meets the application environment.

Crystals Part Context

This part belongs to the family of low-profile SMD crystals designed for general-purpose timing applications. It serves as a passive frequency-determining element in oscillator circuits, providing stable clock signals for digital systems. The 2-SMD package facilitates automated assembly processes.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. When seeking replacements, ensure the alternative matches the 40 MHz frequency, 12 pF load capacitance, 50 Ohm ESR, and 2-SMD package dimensions.
