Crystals Procurement Notes

Verify the specific suffix 'IKT' against the manufacturer's latest datasheet to confirm package and tape/reel specifications. Check current part status as availability may vary by distributor. Ensure compatibility with existing PCB footprint and reflow soldering profiles defined for the 4-SMD form factor.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with 8pF load capacitance is required. Consider the ±10ppm stability requirement relative to system clock accuracy needs. Verify that the -20°C to +70°C operating range meets environmental constraints. Compare ESR of 100 Ohms against oscillator circuit drive level limitations.

Crystals Part Context
