Crystals Procurement Notes

Verify the specific suffix D against official manufacturer documentation to confirm pinout and electrical characteristics match system requirements. Ensure PCB land pattern aligns with the 4-SMD 7x5 mm footprint specifications. Confirm that the 18 pF load capacitance matches the oscillator circuit design parameters before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 16.384 MHz timing source is required in a compact surface-mount form factor. The 18 pF load capacitance and 40 Ohm ESR must be compatible with the host oscillator circuit's input capacitance and drive level constraints. Consider the -20°C to +70°C operating range against the intended application environment.
