Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official part number guide to ensure correct packaging and specifications. Confirm that the required load capacitance matches the circuit design parameters. Check current availability status as supply levels may fluctuate. Ensure the selected variant meets all necessary regulatory compliance requirements for the target market.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with ±10 ppm stability is required within the -20°C to +70°C range. Consider the 80 Ohm ESR value for oscillator circuit compatibility. The small 2.00 mm x 1.60 mm footprint makes it suitable for space-constrained PCB layouts. Verify that the 10 pF load capacitance aligns with the host oscillator's design specifications.

Crystals Part Context

This part belongs to the 8Y series of high-accuracy quartz crystals from TXC Corporation. The series offers various frequency options in a standardized small SMD package. It serves as a cost-effective timing solution for applications where moderate stability suffices. The 8Y series is widely used in general electronic devices requiring reliable clock signals.

Crystals Replacement Considerations
