Crystals Procurement Notes

Verify the specific suffix 'K' indicates the 8pF load capacitance variant, as other suffixes in the 445 series denote different values. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory statuses can vary by production batch. Ensure the ordering information matches the required electrical parameters before finalizing procurement.

Crystals Selection Notes

Select this component when an 8pF load capacitance is required for the 12 MHz application. Compare ESR and drive level specifications against the host oscillator circuit requirements to ensure stable oscillation. Verify that the operating temperature range of -20°C to +70°C aligns with the intended environment. Consider physical size constraints relative to the 5.00mm x 3.20mm package dimensions.

Crystals Part Context

This part belongs to the 445 Series of glass-sealed crystals from CTS-Frequency Controls. The series offers various load capacitances and frequencies in a standardized SMD package. The 'C' prefix typically denotes standard commercial grade performance, while the 'K' suffix specifies the 8pF load capacitance parameter distinct from other variants like 'I' or 'W'.

Crystals Replacement Considerations

Direct substitutes include 445A22K12M00000 and 445I25K12M00000 from CTS-Frequency Controls. These parts share similar electrical characteristics but may differ in manufacturing lot or specific quality grades. Cross-manufacturer replacements require verification of pin compatibility, load capacitance, and frequency tolerance.
