Crystals Procurement Notes

Verify the specific suffix 'ILR' against official CTS documentation to confirm tape and reel packaging specifications. Ensure the load capacitance requirement matches the target circuit design. Confirm availability status as distribution data may vary. 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 frequency is required in a compact SMD form factor. The 12pF load capacitance must align with the host oscillator's specified load. Consider the 100 Ohm ESR for drive level sensitivity. Verify that the ±20ppm stability meets the system's timing accuracy needs within the -40°C to +85°C operational range.

Crystals Part Context

This part belongs to the CTS 402 series of high-frequency crystals. The series offers various frequencies in small surface-mount packages. The 402F27122ILR specifically targets applications requiring stable 27.12 MHz timing in space-constrained designs. It shares the physical footprint with other frequencies in the 402 family, facilitating board layout standardization.

Crystals Replacement Considerations

Direct substitutes include 402F27122IAR and 402F27122IJR from CTS-Frequency Controls. These variants share identical electrical parameters but differ in packaging or reel specifications. Verify compatibility with existing assembly processes before substitution.
