Crystals Procurement Notes

Verify the specific suffix 'CLT' against official CTS documentation to confirm tape-and-reel packaging and lead-free status. Ensure the design-in load capacitance matches the 12pF specification to maintain frequency accuracy. Cross-reference the 100 Ohm ESR value with the oscillator circuit requirements to guarantee reliable startup conditions.

Crystals Selection Notes

Select this component when a small footprint is required alongside moderate frequency stability. The 12pF load capacitance dictates PCB trace and pin capacitance calculations. Verify that the operating temperature range of -20°C to +70°C meets the environmental constraints of the target application before finalizing the bill of materials.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers various SMD crystal options. The 402F250XXCLT specifically addresses the need for 25 MHz timing in space-constrained designs. It shares the same physical envelope as other frequencies in the series but differs in electrical parameters such as ESR and load capacitance.

Crystals Replacement Considerations

Consult the official CTS 402 Series datasheet for direct substitutes with identical 25 MHz frequency, 12pF load capacitance, and 4-SMD dimensions. Verify that any alternative maintains the ±15ppm tolerance and 100 Ohm ESR specifications.
