Crystals Procurement Notes

Verify the specific suffix 'EII' against official TXC documentation to confirm exact load capacitance and tolerance specifications. Ensure compatibility with reflow soldering profiles suitable for seam-sealed crystals. Confirm RoHS compliance status through current manufacturer declarations prior to integration into regulated products.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required in a minimal 3.2x2.5 mm package. Consider the ±30 ppm tolerance for general timing applications where higher precision is not critical. Evaluate thermal performance within the -40°C to +85°C range to ensure stability under operational conditions.
