Crystals Procurement Notes

Verify the specific suffix 'CJT' against the manufacturer datasheet to confirm exact electrical parameters and packaging configuration. Ensure compatibility with reflow soldering profiles specified for ceramic packages. Confirm availability status as distribution channels may list discontinued or obsolete inventory levels that do not reflect current manufacturing production.

Crystals Selection Notes

Select this component when a 30.72 MHz reference is required in a compact surface mount form factor. The 9 pF load capacitance must match the oscillator circuit design requirements. Consider the 80 Ohm series resistance for drive level limitations. Verify thermal performance meets the application's operating temperature range constraints.

Crystals Part Context

This part belongs to the CTS Model 402 series of sub-miniature surface mount crystals. The series utilizes hermetic ceramic packages designed for high reliability applications. The 402 series covers various frequencies within the 16 MHz to 96 MHz range, offering standard tolerances suitable for general digital timing needs.

Crystals Replacement Considerations

Direct substitutes include other 30.72 MHz SMD crystals with identical 2.0x1.6mm dimensions and 9pF load capacitance. Verify pinout compatibility and hermetic sealing requirements before substitution.
