Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct load capacitance and tolerance specifications. Confirm that the required frequency stability meets system requirements before procurement. Check current availability status as supply levels may fluctuate. Ensure compatibility with standard SMT reflow profiles during assembly planning.

Crystals Selection Notes

Select this component when a 40 MHz fundamental mode crystal is required with tight ±20 ppm stability. The 8 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The small footprint suits space-constrained PCB layouts. Verify thermal performance if ambient temperatures exceed standard commercial limits.

Crystals Part Context

This part belongs to the TXC 7V series of miniature surface-mount crystals. The series offers various frequency options in a standardized 3.2x2.5mm package. It serves as a cost-effective timing solution for consumer electronics and industrial applications where moderate stability is sufficient.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz SC-cut crystals in 3.2x2.5mm packages with matching 8 pF load capacitance and ±20 ppm stability. Verify ESR values and drive level specifications to ensure circuit compatibility without redesign.
