Crystals Procurement Notes

Verify the specific suffix 'K' against the official CTS datasheet to confirm the exact load capacitance and tolerance specifications. Ensure the selected variant matches the required PCB footprint dimensions of 5.00mm x 3.20mm. Confirm that the operating temperature range of -10°C to +60°C aligns with the target application environment before finalizing the procurement order.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required in a compact 2-SMD form factor. The 8 pF load capacitance specification must match the oscillator circuit design. Consider the -10°C to +60°C temperature range limitations for industrial applications requiring wider thermal stability.

Crystals Part Context

This part belongs to the 445 Series of glass-sealed crystals from CTS-Frequency Controls. The series provides reliable timing solutions in standard surface-mount packages. The 445C35K12M00000 specifically targets applications needing a 12 MHz reference signal with moderate stability requirements.

Crystals Replacement Considerations

Direct substitutes within the same series include other 445 variants with matching 12 MHz frequency and 8 pF load capacitance. Verify package compatibility and electrical parameters before substitution.
