Crystals Procurement Notes

Verify the specific suffix 'IDR' against the manufacturer datasheet to confirm tape and reel packaging requirements. Ensure the load capacitance matches the target oscillator circuit design. Check current availability status as supply levels may vary. Confirm that the 100 Ohm ESR is compatible with the driving circuit constraints. Validate compliance requirements such as RoHS3 for the intended market.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with moderate stability needs. The 18 pF load capacitance must align with the host circuit's stray capacitance. Consider the 4-SMD footprint dimensions for PCB layout constraints. Evaluate the ±20 ppm tolerance against system timing accuracy requirements. Compare ESR specifications with oscillator driver strength capabilities.
