Crystals Procurement Notes

Verify the specific ordering suffix 'CKT' against the manufacturer's current datasheet to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the RoHS3 status aligns with environmental compliance requirements for the target assembly process. Check for any recent product lifecycle notices regarding obsolescence or replacement recommendations from CTS-Frequency Controls.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with ±10 ppm stability is required in a compact SMD footprint. Ensure the circuit design supports an 8 pF load capacitance to maintain accuracy. Verify that the operating environment remains within the specified -20°C to +70°C range and that the 100 Ohm ESR is acceptable for the oscillator circuit design.
