Crystals Procurement Notes

Verify the specific suffix 'IJT' against the official CTS datasheet to confirm tape and reel packaging specifications. Ensure the 9pF load capacitance matches the target circuit design requirements. Check current availability status as distribution channels may vary. Confirm RoHS3 compliance if required for environmental regulations.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±20 ppm stability. The 9pF load capacitance must align with the oscillator circuit's external capacitors. Consider the 100 Ohm ESR for drive level sensitivity. The small 2.00x1.60mm footprint is suitable for space-constrained PCB layouts.
