Crystals Procurement Notes

Verify the specific suffix 'CLR' against the manufacturer's current datasheet to confirm package and tolerance specifications. Ensure the load capacitance requirement matches the circuit design. Check for RoHS compliance status as per the latest environmental declarations. Confirm availability through authorized distributors, noting that stock levels may vary.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±15 ppm tolerance. The 12 pF load capacitance must align with the oscillator circuit's input and output capacitance. The 100 Ohm ESR value should be compatible with the driving circuit's power limits. Consider the 4-SMD package size for PCB layout constraints.
