Crystals Procurement Notes

Verify the specific suffix 'MAAJ' against official TXC documentation to confirm the exact load capacitance of 18 pF and ESR of 60 Ohms. Ensure the ordering quantity aligns with the manufacturer's standard packing quantity of 3,000 units per reel. Confirm that the 4-SMD footprint matches the target PCB design constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with moderate stability requirements. The 18 pF load capacitance must match the oscillator circuit design specifications. Consider the 60 Ohm ESR value for drive level sensitivity analysis. This part is suitable for applications where space is limited due to its compact SMD form factor.

Crystals Part Context

This component belongs to the 7V series of ceramic crystals from TXC Corporation. The series is characterized by small size and low cost, targeting high-volume consumer electronics. The 7V series provides reliable performance for general-purpose timing applications in digital systems requiring stable clock signals.

Crystals Replacement Considerations

The 7V-40.000MAHJ-T is a documented substitute with identical frequency but different load capacitance (18pF vs 18pF noted in some contexts, verify datasheet). Cross-reference electrical parameters strictly before substitution.
