Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm availability status as distribution channels may list discontinued or backorder items. Cross-reference the package dimensions and pin configuration with PCB footprint libraries prior to procurement to prevent assembly errors. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 38.4 MHz applications with tight ±10 ppm stability constraints. The 18 pF load capacitance must match the oscillator circuit design parameters. Consider the 60 Ohm ESR for drive level sensitivity. The -20°C to +70°C operating range suits standard commercial environments. Evaluate the small 2.00mm x 1.60mm footprint against available board space constraints.

Crystals Part Context
