Crystals Procurement Notes

Verify the specific suffix 'B' against official CTS documentation to confirm exact electrical tolerances and aging rates, as generic listings may not reflect precise variant specifications. Ensure the required load capacitance matches the target circuit design before procurement. Confirm RoHS compliance status through the manufacturer's current datasheet rather than relying on distributor summaries.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with ±30 ppm stability is required for surface-mount applications. The 18 pF load capacitance must align with the oscillator circuit's input and output capacitance values. Consider the 40 Ohm ESR limit to ensure reliable startup conditions within the specified -20°C to +70°C operating temperature range.

Crystals Part Context

This part belongs to the CTS 445 series of surface-mount crystals. The series provides standard frequency control solutions for consumer and industrial electronics. The 445C33B16M00000 specifically denotes a 16 MHz unit with defined tolerance and packaging characteristics within this product line.

Crystals Replacement Considerations

Direct substitutes include other 16 MHz SMD crystals with matching 18 pF load capacitance and similar physical dimensions. Verify that alternative parts meet the same ±30 ppm stability and 40 Ohm ESR requirements to maintain circuit performance.
