Crystals Procurement Notes

Verify the specific load capacitance requirement of your application circuit against the component's 10 pF specification to ensure accurate frequency performance. Confirm that the operating environment remains within the stated -20°C to +70°C range. Check current availability status as supply conditions may vary. Ensure proper handling procedures are followed during surface-mount placement to maintain mechanical integrity.

Crystals Selection Notes

Select this component when a 30 MHz fundamental mode crystal is required with ±20 ppm stability. The 10 pF load capacitance must match the oscillator circuit design. Consider the 80 Ohm ESR limit for drive level sensitivity. The 4-SMD package size suits space-constrained PCB layouts. Verify thermal requirements align with the commercial temperature grade.
