Crystals Procurement Notes

Verify the specific suffix IKR against official CTS documentation to confirm package dimensions and lead finish specifications. Ensure compatibility with reflow soldering profiles defined in the datasheet. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the ESR value of 100 Ohms with oscillator circuit requirements to ensure proper startup conditions.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental mode crystal is required with low phase noise characteristics. The 8pF load capacitance must match the oscillator circuit design. Consider the 100 Ohm ESR limit for drive level sensitivity. The 402W form factor offers space efficiency compared to larger through-hole alternatives while maintaining standard SMD mounting capabilities.
