Crystals Procurement Notes

Verify the specific suffix 'CLT' against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure that the required load capacitance matches the circuit design requirements. Confirm availability status through authorized distributors as supply levels may vary. Cross-reference the ESR value with oscillator circuit capabilities to ensure proper startup conditions.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental mode crystal is required in a compact SMD form factor. Consider the ±10 ppm tolerance and 12 pF load capacitance compatibility with the target oscillator circuit. Evaluate the -20°C to +70°C temperature range against operational environment constraints. Compare physical dimensions against board space limitations before finalizing the design.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for surface mount technology. These components are designed for general frequency control applications where standard stability and small footprint are prioritized over automotive or high-reliability industrial specifications.

Crystals Replacement Considerations

Official substitutes include 402F27111CAR and 402F27111CJR from CTS-Frequency Controls. Verify that alternative parts match the 12 pF load capacitance and 27.12 MHz frequency. Check package compatibility and pin configuration if switching between different suffix variants within the same series.
