Crystals Procurement Notes

Verify the specific suffix 'CJT' against official CTS datasheets to confirm the exact frequency tolerance and packaging configuration. Ensure compatibility with the target circuit's load capacitance requirements of 9pF. Check for availability status as distribution channels may vary. Confirm RoHS3 compliance if required by project specifications. Validate pinout and mounting dimensions against PCB footprint designs.

Crystals Selection Notes

Select this component when a 27.12 MHz reference with ±10ppm stability is required in a small form factor. The 4-SMD package suits automated assembly processes. Consider the 100 Ohm ESR value for oscillator circuit design. The -20°C to 70°C range fits standard commercial applications. Compare against other 402 series variants if different frequencies or tolerances are needed.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages. The 402F27111CJT specifically targets applications needing 27.12 MHz.
