Crystals Procurement Notes

Verify the specific ordering suffix 'IAR' against the manufacturer's current datasheet to confirm package and tape/reel specifications. Ensure the load capacitance requirement of the target circuit matches the 10pF specification. Confirm that the 100 Ohm ESR aligns with the oscillator circuit design parameters before finalizing procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental mode crystal is required in a compact 2.00mm x 1.60mm SMD footprint. The 10pF load capacitance and 100 Ohm ESR must be compatible with the host oscillator circuit. Consider the ±20ppm stability limit and the -40°C to +85°C operating temperature range for environmental suitability.

Crystals Part Context

This part belongs to the CTS 402 Series of general-purpose crystals. The series offers various frequencies and packages optimized for consumer electronics and industrial applications. The 402F27022IAR specifically provides a standard 27 MHz output in a small form factor suitable for space-constrained printed circuit board designs.

Crystals Replacement Considerations

Direct substitutes include other 27 MHz crystals from the same series with identical electrical parameters and package dimensions. Verify that any replacement maintains the 10pF load capacitance and 100 Ohm ESR values to ensure circuit compatibility.
