Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance and stability specifications. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint. Cross-reference the temperature range requirements with the application environment to ensure reliable performance within the specified -20°C to +70°C limits.

Crystals Selection Notes

Select this component when a fundamental mode crystal with 100 Ohm ESR is required for 20 MHz applications. Consider the ±10 ppm stability requirement against system clock accuracy needs. Evaluate the 4-pin SMD form factor against available board space and reflow soldering capabilities. Ensure the load capacitance matches the oscillator circuit design parameters for optimal frequency accuracy.
