Crystals Procurement Notes

Verify the specific suffix 'I' against official CTS documentation to confirm intended function or grade. Ensure the required load capacitance matches the circuit design. Confirm that the operating temperature range meets application requirements. Check for updated datasheet revisions before finalizing specifications.

Crystals Selection Notes

Select this component when a precise 12.288 MHz reference is required for digital circuits. The ±10 ppm tolerance offers higher precision than standard general-purpose crystals. Verify that the PCB footprint accommodates the 5.00 x 3.20 mm package dimensions and that the mounting pads align with the 4-SMD no-lead configuration.

Crystals Part Context

This component belongs to the 405 Series of surface mount crystals from CTS-Frequency Controls. The series provides various frequency options in standardized SMD packages. This specific variant targets applications requiring high frequency accuracy within a compact form factor suitable for modern electronic assemblies.

Crystals Replacement Considerations

Direct substitutes include other 12.288 MHz crystals with identical 12 pF load capacitance and similar ESR values. Cross-reference alternative manufacturers offering 4-SMD packages with matching dimensional constraints. Ensure any replacement maintains the same fundamental mode operation and temperature range.
