Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against the target PCB footprint before integration. Confirm that the 9 pF load capacitance aligns with the host circuit's design requirements to ensure accurate frequency operation. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure storage conditions meet moisture sensitivity level specifications prior to reflow soldering.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with tight ±10 ppm stability is required in a small form factor. Compare the 50 Ohm ESR against the oscillator circuit's drive level limitations to prevent over-driving the crystal. Consider the 4-SMD No Lead package for automated assembly efficiency. Evaluate thermal performance if the application operates near the upper limits of the specified temperature range.

Crystals Part Context

This part belongs to the TXC 7M series of surface-mount crystals, which are designed for general-purpose timing applications. The series offers various frequency options and stability grades, with the MEEC suffix indicating specific electrical parameters including the 9 pF load capacitance and 50 Ohm ESR.
