Crystals Procurement Notes

Verify the specific suffix EC27 against official Suntsu documentation to confirm exact tolerance and stability ratings. Ensure the 4-SMD footprint matches the target PCB layout. Confirm active status and RoHS compliance through current manufacturer datasheets before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 48 MHz reference with ±15 ppm tolerance is required. The 18 pF load capacitance must align with the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. Evaluate thermal performance if operating near the upper limit of the commercial range.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequencies and packages. The SXT21418EC27 variant specifically targets applications requiring precise 48 MHz timing in space-constrained designs. It serves as a standard timing element for digital logic synchronization.

Crystals Replacement Considerations

Direct substitutes include other 48 MHz crystals with identical 4-SMD footprints and 18 pF load capacitance. Verify that replacement parts meet or exceed the ±15 ppm tolerance and 60 Ohm ESR requirements. Check compatibility with existing oscillator circuit parameters.
