Crystals Procurement Notes

Verify the complete part number against manufacturer datasheets to confirm frequency and tolerance specifications. Ensure compatibility with PCB footprint dimensions and soldering thermal profiles. Cross-reference RoHS compliance status if required by project regulations.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±25ppm stability is required. Consider the 12pF load capacitance requirement for circuit design matching. Evaluate the 40 Ohm ESR limit against the oscillator driver circuit capabilities to ensure reliable startup.

Crystals Part Context

This part belongs to the family of surface-mount crystal resonators manufactured by HKC. It serves as a passive frequency-determining element rather than an active oscillator. The designation indicates specific electrical parameters including frequency, tolerance, and package type.

Crystals Replacement Considerations

Substitute parts must match the 40 MHz frequency, 12pF load capacitance, and 4-SMD package dimensions. Verify that alternative components meet or exceed the ±25ppm tolerance and 40 Ohm ESR requirements for functional equivalence.
