Crystals Procurement Notes

Verify the specific suffix CAT against official CTS documentation to confirm exact packaging and handling specifications. Ensure compatibility with reflow soldering profiles defined in the manufacturer datasheet. Confirm that the 10 pF load capacitance matches the oscillator circuit design requirements. Check for any end-of-life notices or obsolescence warnings prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a 30.72 MHz frequency with ±10 ppm stability is required in a compact SMD form factor. The 10 pF load capacitance and 80 Ohm ESR must align with the host oscillator circuit's parasitic capacitance and drive level constraints. Consider the -20°C to +70°C temperature range against application environmental conditions. Compare against alternative packages if board space allows for different dimensional requirements.
