Crystals Procurement Notes

Verify the specific suffix 'IAT' against official CTS documentation to confirm the exact packaging type and tape specifications. Ensure that the load capacitance requirements of the target oscillator circuit align with the 10pF specification to maintain frequency accuracy. Confirm RoHS compliance status through the manufacturer's current environmental declarations before final procurement.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required in a compact SMD footprint. The ±20 ppm tolerance suits applications needing moderate precision without the cost of higher-grade oscillators. Consider the 60 Ohm ESR value to ensure compatibility with the driving circuit's gain margin. Evaluate the -40°C to +85°C range against the operational environment constraints.
