Crystals Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel specifications. Ensure compatibility with the target load capacitance requirements of the host circuit design. Confirm RoHS compliance status if environmental regulations apply to the final product assembly. Cross-reference the manufacturer part number against official distributor catalogs to validate current availability and authenticity before procurement.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental resonance is required with tight ±20ppm stability. The 100 Ohm ESR rating suits applications requiring moderate drive levels. The 1.60mm x 1.20mm footprint is appropriate for space-constrained PCB layouts. Consider the operating temperature range limits to ensure reliability under expected environmental conditions during system operation.

Crystals Part Context

This crystal belongs to the 402 Series from CTS-Frequency Controls, which offers various fundamental mode resonators in small SMD packages. The series provides options for different frequencies, load capacitances, and stability grades. The 402F27122IDR specifically addresses needs for stable timing references in compact electronics where space efficiency and reliable frequency accuracy are critical design parameters.

Crystals Replacement Considerations

Direct substitutes include other 27.12 MHz crystals with matching 18pF load capacitance and similar ESR values.
