Crystals Procurement Notes

Verify the specific suffix 'XCET' against the official CTS datasheet to confirm packaging and tape specifications. Ensure compatibility with standard SMT reflow profiles. Confirm RoHS compliance status through current manufacturer documentation prior to integration into production assemblies.

Crystals Selection Notes

Select this component when a 12 MHz fundamental mode crystal is required in a 5.0x3.2mm package. The 8pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR limit for driver strength requirements. This part is suitable for general-purpose digital logic timing where moderate stability suffices.

Crystals Part Context

This model belongs to the CTS 435 Series of surface mount crystals. The series offers various frequencies and packages optimized for automated assembly. The 435F variant specifically denotes fundamental mode operation within this standardized product line, providing a balance between size, cost, and performance for mass-produced electronics.

Crystals Replacement Considerations

Direct substitutes include other 12MHz 5.0x3.2mm SMD crystals with matching 8pF load capacitance and similar ESR values. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
