Crystals Procurement Notes

Verify the specific suffix requirements against the official CTS datasheet before ordering, as packaging and tape specifications may vary. Confirm that the 9pF load capacitance matches your circuit design requirements. Check current availability status through authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS3 regulations if required by your manufacturing standards. Validate the operating temperature range suitability for your final application environment.

Crystals Selection Notes

Select this component when a 50 MHz fundamental mode crystal is required with ±15ppm stability. The 9pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 4-SMD package size constraints for PCB layout. Evaluate the 60 Ohm ESR against the oscillator driver strength. Compare against other 402 series variants if different frequencies or tolerances are needed.
