• Wearable devices with limited board space

Crystals Procurement Notes

Verify the specific suffix 'BZC' against official datasheets to confirm the 9 pF load capacitance variant, as TXC uses distinct letters for different capacitance values. Ensure the order quantity aligns with standard reel packaging requirements. Confirm RoHS compliance status for the specific production batch prior to integration into regulated assemblies.

Crystals Selection Notes

Select this component when a 9 pF load capacitance matches the MCU's external capacitor configuration. Verify that the ±20 ppm initial tolerance meets the system's long-term accuracy budget. Consider the AEC-Q200 certification if the application targets automotive environments. Compare ESR limits against the oscillator circuit's drive level capabilities to ensure reliable startup.

Crystals Part Context

This part belongs to the AH series of thin-film or standard quartz crystals from TXC Corporation. The series is engineered for low-profile surface-mount applications. It serves as a frequency reference for microcontrollers and dedicated RTC chips. The 32.768 kHz frequency is standard for binary division to one-second intervals.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 32.768 kHz crystals having identical 9 pF load capacitance and 3.2x1.5 mm dimensions. Verify pin compatibility and electrical parameters before substitution.
