Crystals Procurement Notes

Verify the specific suffix CAR against official CTS documentation to confirm tape and reel packaging specifications. Confirm that the 10 pF load capacitance matches the target circuit design requirements. Check current availability status as supply conditions may vary. Ensure the operating temperature range meets the environmental constraints of the final application.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental frequency is required with ±30 ppm stability. The 100 Ohm ESR value must be compatible with the oscillator circuit's drive level limitations. Consider the 2.00 mm x 1.60 mm package size for PCB layout constraints. Verify compatibility with standard surface mount reflow profiles.
