Crystals Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 4-SMD no-lead package aligns with your PCB footprint and reflow soldering profiles. Ensure the manufacturer's datasheet specifications are current, as component parameters may be subject to revision without notice.

Crystals Selection Notes

Select this component when a 27 MHz reference signal is required in a space-constrained environment. The 10 pF load capacitance must match the oscillator circuit's external capacitor values to achieve the specified accuracy. Consider the ±15 ppm tolerance if higher precision is needed for long-term stability or temperature compensation.

Crystals Part Context

This part belongs to the C1E series of surface-mount crystals from Aker Technology USA. The series offers various frequencies and package sizes, with the C1E specifically denoting a 2.0 x 1.6 mm SMD seam seal crystal. Similar parts include the C3E series for different form factors.

Crystals Replacement Considerations

Direct substitutes may include other 27 MHz SMD crystals with identical 10 pF load capacitance and 4-SMD no-lead packaging. Verify mechanical dimensions and electrical parameters such as ESR and shunt capacitance to ensure compatibility with existing oscillator designs.
