Crystals Procurement Notes

Verify that the ordering suffix matches the required load capacitance and stability specifications. Confirm the package type aligns with PCB footprint requirements. Ensure compliance with RoHS directives if restricted substances are prohibited in the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar frequency variants.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with high frequency accuracy. The 10 pF load capacitance must match the oscillator circuit design parameters. Consider the 30 Ohm series resistance for drive level limitations. The SMD3225-4P form factor is suitable for automated pick-and-place manufacturing processes.

Crystals Part Context

This crystal belongs to the family of passive quartz resonators used for frequency generation. Unlike active oscillators, it requires an external oscillator circuit to function. The SMD3225-4P package is a common industry standard for space-constrained designs. It serves as a critical timing element in microcontroller-based systems.

Crystals Replacement Considerations

Substitute only with identical 40 MHz crystals sharing the same 10 pF load capacitance and SMD3225-4P footprint. Verify that alternative suppliers offer equivalent ±10 ppm tolerance and ±30 ppm stability ratings. Ensure the replacement maintains the same fundamental mode operation and series resistance characteristics.
