Crystals Procurement Notes

Verify the exact datasheet specifications against the manufacturer's official documentation before procurement. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint requirements. Ensure the 12 MHz frequency and ±30ppm tolerance meet your system's clock accuracy needs. Check for any specific reflow soldering profile recommendations provided by Geyer Electronic to ensure reliable assembly.

Crystals Selection Notes

Select this component when a 12 MHz reference signal is required with moderate stability. The 18pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The SMD package facilitates automated assembly. Verify temperature range requirements if operating outside standard commercial limits.
