Crystals Procurement Notes

Verify the specific suffix 'I25L' against official CTS documentation to confirm exact load capacitance and stability ratings, as generic series data may vary. Ensure the requested variant matches the required temperature range and ESR specifications for the target circuit. Cross-reference the manufacturer part number directly with the datasheet to avoid substitution errors due to similar naming conventions within the 445 family.

Crystals Selection Notes

Select this component when a precise 14.31818 MHz reference is required for digital systems. The ±20 ppm tolerance suits applications needing stable timing without active compensation. Verify that the system impedance matches the Series load capacitance specification. Consider the physical dimensions and mounting style for PCB layout constraints. Confirm environmental requirements align with the -20°C to +70°C operational range.

Crystals Part Context

This part belongs to the CTS 445 Series of glass-sealed quartz crystals. These components are designed for high reliability in surface-mount applications. The series offers various frequency options and packaging styles. The 445I25L variant specifically targets standard digital logic interfaces.
