Crystals Procurement Notes

Verify the specific load capacitance and ESR values against your circuit schematic before ordering. Confirm that the operating temperature range meets your environmental requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the package dimensions match your PCB footprint constraints. Contact the manufacturer or authorized distributors for current availability and lead times as this component may have long supply cycles.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is needed for timekeeping functions. Consider the high ESR value which limits the drive level and requires appropriate oscillator circuit design. Evaluate the thermal stability characteristics if the application involves significant temperature fluctuations. Compare alternative packages if space constraints differ from the standard SMD form factor provided by this model.

Crystals Part Context

This component belongs to the family of precision timing crystals manufactured by CTS-Frequency Controls. These parts are engineered for applications requiring accurate frequency generation over extended periods. The tuning fork design distinguishes it from bulk acoustic wave resonators used in higher frequency ranges. This specific model targets the ubiquitous 32.768 kHz niche common in digital clocks and embedded systems.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and similar ESR specifications. Verify that any replacement maintains the same operating temperature range and package outline. Cross-reference with other manufacturers' tuning fork crystals to ensure pin compatibility and electrical equivalence.
