Crystals Procurement Notes

Verify the specific suffix 'K' against official Epson documentation to confirm the 10pF load capacitance and ±100ppm tolerance specifications. Ensure the procurement source provides valid traceability data, as this component type may have limited availability or be subject to end-of-life notices depending on production batches. Cross-reference the datasheet revision to confirm current manufacturing status.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with ±100 ppm stability is required in a small form factor. The 10 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range for standard commercial applications. Verify that the 100 Ohm ESR aligns with the driving circuit requirements to ensure stable oscillation without overdriving the crystal.
